Torontohenge October 2017– Best Photo Ops

The last Torontohenge of 2017 is coming up…

Torontohenge is the name given for the phenomenon that occurs when the sun rises or sets in line with Toronto's major east-west streets downtown, giving photographers a great opportunity to capture the sun as its top edge grazes the horizon between the canyon walls of buildings on either side of the street.

Although Torontohenge technically falls on the dates given below for 2017, great photos can be taken for about a week before the August and October dates and a week after the February and April dates as the sun hovers directly above the street.  Not great for driving, but quite a sight just the same.

Best Photo Ops in October
In October, great photo ops will occur before the 25th.  For example, the sun will cross, and be perched above, the street at about 6:12 PM on the 21st and 6:15 PM on the 23rd.
In a nutshell, there will be opportunities for great photos between now and the official Torontohenge date of October 25th.

The Torontohenge dates for 2017 are:

Sunrise Sunset
Feb 15           5:48 PM
Apr 19      6:28 AM
Aug 23      6:31 AM
Oct 25           6:18 PM

Best Photo Ops in August

In August, the best photo ops will occur before the 23rd.  For example, on the 22nd the sun will break loose from the horizon at about 6:33 AM and sit fully above the street. 

Similarly, the rising sun will cross the street and be fully perched above it at about 6:35 AM on the 21st, 6:37 AM on the 20th, 6:38 AM on the 19th, etc.

On August 16th, a full week before Torontohenge, the sun will cross the street at about 6:43 AM at a height of about 2.5 degrees above the horizon (i.e. about the width of your thumb at arm’s length).
Tomorrow morning, August 13th, the sun will cross at about 6:47 AM at a height of about 3.8 degrees.

In a nutshell, there will be many opportunities for great photos between now and the official Torontohenge date of August 23rd.

The Torontohenge dates for 2017 are:

Sunrise Sunset
Feb 15           5:48 PM
Apr 19      6:28 AM
Aug 23      6:31 AM
Oct 25           6:18 PM

Province House National Historic Site

"The story of Canada as a confederation began in this historic Charlottetown building. In September 1864, Province House was the scene of the first conference on colonial union. Delegates from the colonies of Prince Edward Island, New Brunswick, Nova Scotia, and Canada met in the legislative council chamber to begin discussions, which led to confederation in 1867." (Source: Parks Canada)

Province House, a National Historic Site operated by Parks Canada, is the official birthplace of Canada.  Province House is a Charlottetown landmark.

On July 1, 2017, Canada celebrates its 150th birthday.  At 1:16 PM Atlantic Daylight Time, the sun passes directly over Province House - more specifically, the sun crosses the meridian that runs through it.  Solar Noon.  High Noon.  A spotlight shining over Canada's birthplace that can be seen by Canadians from sea to sea to sea.

Join other Canadians celebrating Canada 150 by observing the sun for a moment as it lines up with Province House.  Let this moment unite us all.

Below are the local times in each of Canada's time zones at which to observe the sun as it
