Watching the partial eclipse in Edmonton, Alberta, Canada
To watch the solar eclipse that took place in North America on August 21, 2017, I made my own pinhole projector.
Edmonton saw a partial eclipse with 74% maximum coverage.
- Eclipse began at 10:24 a.m. MDT
- Mideclipse was at 11:35 a.m. MDT
- Eclipse ended at 12:49 p.m. MDT
I made my pinhole projector by cutting up a cereal box, then glued white paper to the viewing panel and poked a hole in the top panel.
Here are images and instructions for a simple card projector on Time and Date.
As an experiment, I tried two hole sizes: one made with a sewing needle and one made with a small picture hook nail. For future reference, the larger hole made with the nail worked much better.
My car windshield was the perfect angle for the bottom panel, onto which the image of the eclipsed sun was projected. The top panel (Cheerios label) was held about 2 1/2 feet above the bottom panel, allowing the sun’s light to project through the pinhole. A bigger distance between the panels created a larger image.
What worked best
- A hole made by a picture hook nail made a larger, easier-to-view image than a pin or needle.
- Holding the top cardboard sheet farther back (2 to 2.5 feet) enlarged the image.
- Not having to hold both panels allowed me freedom of movement with the top panel as well as a free hand with which to take photographs of the pinhole image created.
The day began with a perfectly clear sky. The few white clouds we had that morning held off until after 11:35 a.m., which was mideclipse in Edmonton. They cleared up again near the end of the eclipse, allowing for a final photo of the event. Shortly after the eclipse ended, the sky became cloudy!

Pinhole projector eclipse photos are my own, taken on a Huawei Nova Plus smartphone. Colour and clarity were adjusted using Windows 10 Photos.

My son and my brother drove to the US and saw totality first hand near Rexburg, Idaho. Below is my son’s picture from Instagram:
