Monday, August 21, 2017 -
12:00pm to 4:00pm

On Monday August 21, 2017 a partial solar eclipse will be visible from Hamilton and surrounding areas. This is a wonderful opportunity to see a rare and spectacular natural event. The eclipse will last over 2½ hours, changing in appearance throughout that time, with the greatest amount of the Sun being eclipsed at 2:31 pm. At that time about 76% of the Sun will be blocked.

The Event
The Moon will pass in front of the Sun from our perspective. When this happens it is called a solar eclipse. the Moon is 400 times smaller than the Sun but it is also 400 times closer, so they appear about the same size in the sky.

The Sun will first appear to have a small “bite” taken out of its right hand side a little after 1:09pm. This blocked part of the Sun will appear to grow as the Moon covers more and more of the Sun, until finally at 2:31pm it will appear like the illustration. From then until the eclipse ends the blocked portion of the Sun will shrink as the Sun regains its normal appearance, ending with the last silhouetted part of the Moon disappearing from he left and side of the Sun at 3:39pm.

The Hamilton Amateur Astronomers will be at T.B. McQuestion Park between 12:00 – 4:00pm for the whole event. The eclipse itself will occur at the following times:
• Begins: Mon, Aug 21, 2017 at 1:09pm
• Maximum: Mon, Aug 21, 2017 at 2:31pm
• Ends: Mon, Aug 21, 2017 at 3:49pm
• Duration: 2 hours, 40 minutes
