How quickly does the Sun move?

Did you know...

1) ...the sun's altitude changes most rapidly during early morning and late afternoon hours.

For Toronto...

...typically about 1 degree per hour around noon
...up to about 11 degrees per hour early and late in the day

...the rate of change is greater in summer than winter.

2) ...the sun's direction changes most rapidly around noon.

For Toronto...

...typically about 10 degrees per hour early and late in the day
...up to about 38 degrees per hour at noon on June 21

...the rate of change is much greater in summer than winter.

Sun Glare While Driving – February 2016

The following relate to the dangers of sun glare while driving, and traffic safety in general. They were derived from our twitter feed @SunPosition

Sun Glare Blamed in Windsor Crash  | @NewsRadio1290

Authorities say sun glare may be to blame for a single vehicle crash on Foley Road in Windsor January 31 that sent one man to the hospital for observation. 

Broome County Sheriff’s officials say the 78 year old driver told them the sun glare on his windshield caused him to veer off the road at around 7 p.m.

The man suffered a head injury but was able to get himself out of the vehicle and was sitting at the side of the road when emergency crews arrived…

Accident on causeway bridge ties up traffic for over hour | Barnegat Light Taxpayers’ Association 

The Tuesday commute onto Long Beach Island became a traffic nightmare when three cars crashed right before 8 a.m. – likely a result of early morning sun glare, according to Stafford Township Police Ptl. Chris Fritz.

Stafford police responded to the scene at Route 72 and milepost 28, which is the final bridge before Ship Bottom. Investigation revealed the first vehicle, a pickup truck operated by Christopher Potts, 42, of Manahawkin, was stopped in traffic on Route 72, likely for some construction equipment to move across or around the area. His truck was struck in the rear by a vehicle operated by Thomas Bernabeo, 76, of Manahawkin. A third vehicle, driven by Kathy Guerrero, 46, of Tuckerton, struck the rear of Bernabeo’s vehicle…

Traffic Scotland: Sun glare may be contributing factor >

Second multiple crash at same location on A9 a day apart | BBC

Crashes involving a total of 10 cars have happened close to where eight cars were involved in a collision on Monday.

The first incident involving six cars occurred at about 08:30 on the A9 near Allangrange between the Tore roundabout and Kessock Bridge.

Four cars were caught up in the second accident an hour later at North Kessock, just south of the first crash…

Traffic Scotland has suggested that sun glare may have been a contributing factor in the incident at Allangrange. There were similar conditions on Monday morning.

On Monday eight cars were caught up in two crashes that happened within minutes of each other on the same stretch of the A9.

A woman was injured when six cars collided before 09:00 near the road's Munlochy junction, north of Inverness.

Two cars were involved in the second incident near the scene of the first accident. One of the cars caught fire but no-one was hurt.

The accidents shut the southbound carriageway for several hours.

Insp Neil Lumsden, head of trunk roads policing in the north of Scotland, said a low lying sun had been a contributory factor in both Monday and Tuesday's accidents.

He told BBC Radio Scotland: "In situations of reduced visibility, which drivers have experienced over the last two days, drivers should reduce their speed and extend the distance between themselves and vehicle in front.

"This will not only give drivers time sufficient time to react to what is happening in front of them, but it will also allow them to extend their braking distance."

Three potential killers; a low sun; broken lights and those blind spots | via @Independent_ie

We regularly highlight the main factors behind road crashes. They are speeding, drink driving, non-seatbelt wearing, mobile phone use, drug driving and driver fatigue.

But there are others that, while not principal causes, are equally important to make sure you stay safe. Here are three:

1. The first is magnified at this time of year. It is the danger caused by sun glare. Drivers can be temporarily dazzled or blinded by the intensity and brightness of a low sun on the horizon…

At this time of the year, the sun sits low in the sky in the late morning and early evening. If a driver is driving straight into the sun at these times, he or she can be completely dazzled by the sheer intensity and brightness of its rays. Ray D'Arcy on his radio show recently described such an experience when driving down the main hill on the M8 into Cork just before the Jack Lynch tunnel.

The situation is made worse if the windscreen is dirty or greasy or if it has been raining, or there is snow on the ground.

Don't get caught out by sun glare, make sure your windscreen is clean inside and out. Get a pair of polarised sun glasses. They will help greatly in reducing the effect of sun glare.

2. Another problem is broken headlights…

3. Another danger faced by vulnerable road users, particularly in towns and cities, is the blind spots on trucks. Due to their size and design, trucks have significant blind spots. A driver's field of vision, within a cab, is limited; the area immediately in front, behind and to the left is often hidden from view and cyclists and pedestrians are at an increased risk of being struck…

Bright sun glare questioned >

Jury finds Jasmine Limo fully responsible in car accident trial | Brooklyn Daily Eagle

On a sunny weekday morning in December of 2011 at about 8 a.m., the B63 bus was travelling southbound on Fifth Avenue in Brooklyn. Two of the passengers were standing, waiting to disembark at the next stop. On the bus driver's left, a school crossing guard was shepherding children through the 92nd Street crosswalk. On his right, he noticed an approaching eastbound livery service car. The bus driver claims he had the green light.

At issue in the trial was the determination of liability in the collision that followed. Bright sun glare was brought into question, per the crossing guard's testimony and from the police accident report taken at the scene, though seemingly conflicting statements were made by the limo driver as to whether he had the sun in his eyes…

Police warn of sun glare following five fatal crashes | The Gazette

POLICE are warning drivers to be aware of low sun, after it contributed to five fatal road collisions in the last three years, including one in Basingstoke. 

Hampshire Constabulary said that at this time of year, low sun can prove a real threat to road users.

In the county during the last three years, "vision affected by dazzling sun" was recorded as a contributory factor in five fatal crashes.

This included one in Worting Road, Basingstoke in August 2014 when an 82-year-old pedestrian was hit by car and later died in hospital.

During the same period between 2013 and 2015, there were 60 serious casualties and 360 slight casualties in collisions where sun glare proved to be a factor.

Research shows the majority of these happening during the morning rush hour, between 7am and 9am.

They are also more likely to happen in urban areas rather than rural.

In a bid to reduce these collisions, Sergeant Rob Heard, Hampshire Constabulary’s road safety sergeant, is reminding motorists to be extra careful and has explained how drivers can avoid the dangers of low sun.

He said: “The first thing to be aware of is the increased chance of dazzle when the sun is out.

“You may be aware of the sun coming from a certain direction and as such you may be able to predict it dazzling you as the road direction changes.

“If a certain section of road is always difficult with increased glare then consider taking an alternative route.

“If the sun is low in the sky then make sure you leave extra distance between you and the vehicle in front.

“Drive at a sensible speed for the conditions and visibility allows.

“Avoid sudden and heavy braking as the vehicles behind may also become dazzled as well.

“When approaching junctions be particularly careful as with reduced visibility you or other motorists may not be able to see oncoming vehicles so clearly.”

Other top tips include making sure your windscreen is clean and clear inside and out. The dazzle effect can be made worse when sunlight hits dirt, traffic film, insects or even road spray containing salt.

Consider using your sun visor, but be aware how this can reduce part of your view ahead. Remember that most cars allow you to swivel the sun visor to the right to counter glare coming in from the side window as well.

Sunglasses may also help.

Two die after crash on Stanley road | WHSV

Two people from Stanley are dead after a multi-vehicle crash on West Main Street in Stanley, according to state police. 

The crash happened at about 7:35 a.m. on Wednesday near the intersection of U.S. Route 340 Business and Zion Hill Lane.

Wayne Freeze, 81, was driving eastbound in a 2012 Hyundai Accent approaching a 1998 Jeep Cherokee and when he couldn't see because of sun glare, he swerved into the other lane, according to state police. That's when he hit Rachel Utz, 62, head-on as she drove a 1996 Ford Escort. Freeze then hit the Jeep.

Both Freeze and Utz died, while the driver of the Jeep, 21-year-old Michael Fox, of Stanley, was not injured.

Accidents Caused by Sun Glare - @caraccidentstl  The Hoffmann Law Firm

Sun glare is a hazard for all drivers, at times leading to serious car crashes.

When sight is impaired, a driver is at risk. A vast majority of sun glare accidents occur in intersections and result from blinded drivers who fail to see other drivers or traffic control devices.

Car Accidents Caused by Sun Glare
•A driver is unable to see a traffic light or stop sign and collides with another motor vehicle in the intersection. At high speeds, these accidents can be fatal.
•A driver is unable to see the lane position or the road itself and may drift from the lane. This could cause a side sweep accident or a head-on collision.
•Sun glare can make it difficult for a driver to see other cars on the road, leading to blind spot accidents.
•Sun glare affects a driver’s ability to see the tail lights of the vehicle in front, leading to a rear-end collision when the lead vehicle comes to a stop or slows down.
•A driver fails to notice oncoming traffic and makes a left turn.
•A driver fails to see pedestrians or bicyclists at an intersection.

Sun Glare Is Worst During Rush Hour

It is important to note that sun glare is worst during morning and evening rush hours. During these times, the sun is low and towards the horizon and its angle toward the earth is such that it becomes a hazard to drivers. Here are some tips that will help you avoid accidents caused by sun glare:
•Avoid driving when the windshield is dirty as it can amplify the effect of sun glare. Clean the windows and windshield often and check the windshield fluid level to make sure you do not run out of it when you need it the most.
•Wear sun glasses that have anti-glare properties. This will not just protect you from glare but also from harmful effects of UV rays.
•Do not look directly into the sun or a reflective surface or object.
•Remember, sun glare is a concern not only during the summer, but winter as well. Snow accumulation can also cause glare.
•If glare seems to be obstructing your view, slow down so that you have time to react in case a pedestrian or another vehicle appears in front of you.

Top ten sun glare tips | via @MoneyMarketUK

Occasional sunshine has brought a recent welcome relief to grey, damp mornings and this week is forecast to bring colder, clearer weather: but for drivers the coincidence of sunrise and the morning commute has been blamed for a spate of collisions over recent days. 

The AA points out that the sun rises between 07.30 and 08.00 during late February / early March, when weekday traffic volumes near thier peak.

Max Holdstock, the AA’s Patrol of the Year, says that while early morning sunshine shows the days are getting longer, for motorists it can bring sudden and distressing dazzle.

“Under certain conditions such as topping a gradient from a shady dip, being confronted by the rising sun will temporarily blind drivers as they struggle to find relief with the sun visor.

“A natural tendency is also to brake – which can in turn result in a multiple collision, or lead to a skid on an icy or wet road surface.  Last week this happened with tragic consequences on the M40 near High Wycombe for instance, the A9 north of Inverness and many places between.

“And with clear, cold days forecast throughout the UK, bright sun and potentially icy patches on roads means drivers should take extra care.

“The sun’s glare can be especially intense if it is shining beneath dark cloud cover, with perhaps a wet road surface adding to the dazzle.  If combined with an even slightly dirty windscreen, you simply can’t see what’s ahead.”

According to Department for Transport statistics, vision affected by dazzling sun contributes to around 2%, or nearly 3,000, of road collisions in which people are injured or killed.**

AA Insurance statistics show that there is a peak in car insurance claims during early spring and autumn when sunrise and, to a lesser extent sunset, coincide with high traffic volumes.

Mike Lloyd, director of AA Insurance adds: “Sun glare is usually a contributory, rather than prime, cause of a collision.  For example, driving too close to the vehicle in front is likely to be the principal factor, exacerbated by sun glare when the driver in front is temporarily blinded and hits the brakes.

“If the following driver maintains at least a two-second gap – more if wet or icy – then it’s more likely that he or she would be able to stop in time.  Remember that notwithstanding sun glare, if you hit another vehicle from behind you will almost certainly be considered to be the ‘at fault’ driver, leading to loss of excess and no-claim bonus.

“Fortunately, sun glare is a relatively minor factor in the annual toll of crashes – but such collisions tend to be concentrated in early spring and autumn.

“But every collision and injury is one too many.  A few simple precautions could make the difference between a sickening crunch and safety.”

AA’s top ten sun glare tips

The AA’s Patrol of the Year, Max Holdstock, offers his top ten tips to reduce the effect of sun glare

  1. Keep a safe distance from the vehicle in front: at least two seconds, more if it is wet or icy.
  2. Keep your windscreen spotlessly clean inside and out.  Keep the windscreen wash topped up and check that your wipers are in good condition.
  3. Regularly clean the inside of the screen, it tends to build up a film from the screen demister.  If you are a smoker, the screen will film much more quickly, and can become almost opaque in sun glare
  4. If it’s frosty make sure your screen is properly de-iced before setting off on your journey
  5. Be alert for road conditions where sun glare might be an issue, for example climbing a gradient from a relatively dark dip when driving towards the sun or the road bends towards the sun from a shaded area such as trees or buildings, when the sun may suddenly appear.
  6. Watch for brake lights from cars ahead, suggesting that they might be dazzled
  7. Remember that if you are driving away from the sun, oncoming vehicles may not easily see you.  Keep your headlights on 
  8. If you are suddenly dazzled, don’t use the screen wash – the fluid will simply refract the sunshine into thousands of bright points of light
  9. Keep your sun visor positioned to shade the worst of the dazzle
  10. Keep a clean pair of sunglasses in the car.  If you normally wear glasses, make sure they, too, are spotlessly clean

Motorcycle strikes car at Hurricane High School, glare from sun a factor | St George News

HURRICANE – A collision between a 2004 Lincoln Town Car and a 2012 Honda motorcycle Monday morning at Hurricane High School was caused by glare from the sun and left a 17-year-old boy with minor injuries. 

The accident happened at 8:05 a.m. in the south parking lot of the school where the bus zone intersects with a road coming off 300 West, Hurricane Police Sgt. Brandon Buell said.

The 46-year-old female driver of the Lincoln was coming out of the bus zone area when she pulled in front of the motorcycle, causing the collision.

“The driver said that her view was obstructed due to the sun shining in her eyes and didn’t see the motorcycle,” Buell said…

“If the sun’s blocking our view, then we need to make sure that we take extra precautions to travel slowly and pay attention,” Buell said…

Top floors set back to reduce shadowing >

Mixed-use 6-story building approved on Addison Street | Berkeleyside

A new 69-unit building, with 7,240 square feet of commercial space on the ground floor, has been approved by the city’s zoning board for construction on Addison Street. 

The six-story 60-foot-tall building is the latest development by property owner Avi Nevo, who has developed numerous projects in Berkeley over the last 17 years, including Telegraph Gardens across from Whole Foods…

Local leasing agent John Gordon, who owns the property directly north of the 1931-1935 Addison, wrote a letter in support of the project, noting that he’d met multiple times with Nevo and his architect, and that they had made changes to the project that would lessen the impact on his property.

“Under our agreement the building’s northwest corner and the top level which presented the biggest shadow impact was set back approx. 14 feet from the property line for the top two levels which would reduce the project shadow impact on my property,” he wrote. “In addition the roof parapet was removed and revised to an eave to further reduce the impact.”

During the public comment period at the June 27 zoning board meeting, three residents who work near the proposed project site raised concerns about the project’s potential impacts on sunlight, noise and parking. Two of them asked the zoning board to slow down the process and allow more time for review and mediation…

An appeal dated July 16 and signed by 29 people has been filed, which would require City Council review of the Addison Street project. The appellants — including the East Bay Media Center — have asked for a traffic analysis and more information about future shadowing impacts, as well as for the project height to be dropped to four stories.

RT Scott Dippel ‏@CBCScott Farrell says terracing of the condo building is expensive and that's a nod to minimizing the shadow impact of this 8 story bldg.

Study details impacts of East New York rezoning

Mayor Bill de Blasio’s plan to rezone East New York would leave the neighborhood with a temporary shortage of public school seats and child care facilities, insufficient open space and a prolonged shadow cast over a church, according to a study the city recently released…

The proposed rezoning could also cast a pall, literally, over an historic building in the area, according to the study.

New development could have a “significant adverse shadow impact” on the Holy Trinity Russian Orthodox Church, casting shadows for periods of 36 minutes to nearly three hours. The shadows “may have the potential to affect the enjoyment of [sunlight-sensitive features] from the interior of the church,” the study states. The city determined there were no feasible ways to eliminate the threat…

Concerns rise over Five Points condo | Barrie Examiner

Neighbours to a proposed high-rise development at Barrie's Five Points haven't exactly warmed to the project. 

More than eight years after a massive fire destroyed buildings at the downtown corner, a 20-storey, 203-unit residential, high-density, mixed-use project with ground-floor commercial and parking is being proposed.

A public meeting for the needed rezoning application takes place Monday, and neighbours are already making noise about the development and the variances being requested.

They include an increase to the maximum building height that's currently allowed and a decrease in the required building stepping setback provisions from the lot line...

“This development would give residents on the upper floors of Advance Tech's tower beautiful views and sunlight at the expense of property owners, commercial businesses and residents along Clapperton and Bayfield streets,” she said in a letter to the city.

“Why should neighbouring property owners, residents and businesses be expected to experience undue shade for the benefit of a single developer or their new neighbours? A building of this height would be better suited elsewhere.”…

In 2007, the Province of Ontario amended the Planning Act to allow municipalities the ability to implement a streamlined development approval framework. The new Development Permit By-Law System (DPS) effectively combines zoning, site plan, and minor variance approvals into a single regulatory process. Passed by City Council in 2014—and currently in the midst a lengthy OMB appeal—the DPS is intended to replace Toronto's current site-specific zoning with an area-based approvals process in select areas. Already formally adopted by several municipalities across Ontario, the framework is designed to ensure that each development is in keeping with the planning objectives—and community vision—for its area…

Despite Toronto's stalled progress in implementing the DPS, Chief Planner Jennifer Keesmaat has remained a strong advocate. Writing in her personal blog, Keesmaat calls the system "a significant and potentially transformative change," citing the more community-oriented structure of the system—and its greater transparency and predictability—as improvements over the status quo...
