YEG Partial Eclipse of the Sun

20937786_10158996366205198_1885083462_nEdmonton will be able view a Partial Eclipse of the Sun on Monday, August 21, at 10:24 a.m.

All of North America will be treated to an eclipse of the sun on the morning of August 21.

For us, in Edmonton, we’ll still see a partial solar eclipse, where the moon covers part of the sun’s disk. While it might not be a total eclipse, the visible partial solar eclipse will still be just as brilliant.

For those within the path of totality, where the moon will completely cover the sun and the sun’s tenuous atmosphere (the corona) they will see a total solar eclipse! This path will stretch from Salem, Oregon to Charleston, South Carolina, USA.

Don’t miss out on the chance to experience one of nature’s most awe inspiring sights!

The First Rule of Partial Solar Eclipse Viewing: NEVER watch with the naked eye!

Watching a partial solar eclipse can be a fun and memorable experience, but make sure you take the proper precautions to witness this celestial phenomenon safely and use proper eye protection. Failure to do so could result in permanent eye damage, or in extreme cases, blindness.

Why it’s Dangerous to View a Partial Solar Eclipse with the Naked Eye:

People often assume that because most of the Sun is covered by the Moon during a partial solar eclipse that the Sun is therefore dimmer and safer to look at. This is not true! During a partial solar eclipse, the remaining visible portion of the Sun is just as bright as the uneclipsed whole Sun, and just as capable of causing eye damage.

In fact, the Sun literally burns an image of itself into the retina of the unsuspecting viewer’s eye. This occurs without any sensation of pain, since the retina (the light sensitive layer at the back of the eye) has no nerve endings. People who sustain this type of eye damage see a negative image of the Sun’s disk superimposed on everything they see – or be totally blinded – for the rest of their life! We want the eclipse to leave a lasting impression on your memory, not your retina! So be careful and protect yourself.

Examples of Proper Eye Protection:

  • Solar Eclipse Viewer: This is a pair of cardboard glasses with special safe-solar film.
  • Proper Solar Filter for a Telescope: If you plan on viewing the partial solar eclipse through a telescope, you will still need eye protection! Use a solar filter, fitted for a telescope. Be careful not to put the solar filters at the eyepiece of the telescope. It must be placed securely at the front of the telescope, before the light enters the optical system.
  • #14 (Number Fourteen) Welding Filter: This item is a piece of dark green glass, about 2” tall by 4” wide. The glass filters out much of the visible light – only allowing a very small percentage of sunlight to shine through – therefore protecting your eyes from the harmful invisible radiation. You can purchase #14 Welding Filter at most welding supply stores.
  • Pinhole Projection Method: This method is an easy and rather inexpensive way of watching an eclipse. Here’s how it works: a small hole in an opaque card is used to produce a small image of the solar disk. The only drawback is the brightness of the image is comparatively low, so it’s best to view it in darkened surroundings.

The RASC Observatory (TELUS World of Science – Edmonton
11211 142 Street NW) is hosting FREE viewing beginning at 10:00 a.m. to 1:00 p.m. to safely glimpse the eclipse. Telescopes will be set up for public viewing.

Partial eclipse begins at 10:24 a.m.
Maximum eclipse at 11:35 a.m.
68.4% of the Sun’s area will be obscured by Moon.
Partial eclipse ends at 12:49 p.m.
