Join us on Friday June 9th as we welcome Dr. John Percy, Professor Emeritus, University of Toronto. His topic for the evening will be “Variable Stars, the AAVSO, and You”.

As Dr. Percy describes it, “Variable stars are those stars which change in brightness, which most do — they are “action in the sky”. In this presentation, I will give an overview of variable stars, and how skilled amateur astronomers contribute to their understanding — especially through the American Association of Variable Star Observers (AAVSO). You can, too! I will also briefly describe my current research projects which make use of AAVSO data”.

Observing Director Steve Germann will also be there with the summer edition of The Sky This Month.
We will also be giving away some door prizes. Don’t forget that we gladly accept donations of food or cash for delivery to Hamilton FoodShare. Anything you can spare would be greatly appreciated!

Doors open at 7:00 PM and the meeting begins at 7:30 PM. For those not able to attend in person, we will be livestreaming the meeting on ZOOM for club members and will also be posted on our YouTube channel after the meeting.

We hope to see you there!
