LOCATION CHANGE: Our monthly City Star Party for July has been moved to York University Open Air Astro Fair instead of Bayview Village park. If you don't have a telescope then you will find many astronomers who would love to share a view.
On the weekend of May 2-5, 2025, about 24 Toronto Centre member volunteers participated in the annual Spring Work Party at our E.C. Carr Astronomical Observatory (CAO) on Blue Mountain.
Comet C/2023 A3 (Tsuchinshan–ATLAS) is visible now!
