Solar Eclipse Day Monday August 21. Protect Your Eyes!
Monday, August 21, 2017
A partial solar eclipse will be visible over North America beginning at 10:30am local time, with the sun becoming 75% covered at 11:46am, and then be finished by 1:04pm. Join us for some Eclipse Day fun and learning!
At 10:05am see our Space Show at the Space Stadium Stage on the second floor. This will be a special shortened version to allow you time to get outside for the start of the eclipse. We'll also be giving away solar eclipse viewing glasses after the show at about 10:20am (one pair per family/group, free with your Science Centre Admission while supplies last).
The Royal Astronomical Society of Canada will be outside the Kramer IMAX Theatre entrance with their telescopes with special filters on the lenses to allow safe viewing of the eclipse during the event.
At 2pm after the eclipse, we'll have an extra 2pm Family Activity to enjoy where we'll be drawing the phases of the eclipse with chalk to better understand what's happening. You'll get to take your eclipse drawing home too!
Also here on Monday will be the Saskatchewan Research Council. They're encouraging people of all ages to become Honourary Scientists by turning their kitchens and backyards into science labs and unleashing their inner scientist. They've got three fun and easy science experiments that can be done at home using easy to find supplies, and from 10am-4pm they'll be here to help you build a mini catapult! Tag your results #sciencewithsrc.
Let's all safely enjoy this spectacular celestial event and a great day!
Remember, there is no safe time to look at the eclipse without having protective eyewear on, or through a certified filter (like on the RASC telescopes). View the eclipse only using specifically approved viewers, as you can damage your retinas (affecting your vision) without even knowing it, since we don’t have pain receptors on that part of the eye. Regular glasses, sunglasses, binoculars, telescopes without proper filters, or other unapproved devices can be dangerous as they don’t filter out what’s needed to keep your eyes safe.

Viewing the eclipse improperly can result in solar retinopathy which typically results in crescent shaped burns in the central retinal tissues of one or both eyes. This damage can be temporary or can result in permanent vision loss or even blindness. As the eclipse passes over many places, including Saskatchewan, the moon will not block 100% of the sun. Because so much of its light is blocked by the moon, if one looks at it without full protection, it does not cause pain as looking at the sun typically does. During an eclipse, there is no pain associated with looking at the sun and as such it is easier to stare for a bit....unfortunately, even less than 30 seconds of exposure to a partially eclipsed sun, you can burn a blind spot right in your most precious central vision. Just like sunburn to the skin, the effects are not felt or noticed immediately.
Please take precautions during this solar event.
