Come join us along the Lake Ontario shoreline to safely observe exciting sunspot activity and solar prominences through our solar telescopes! The Sun has been very active lately, producing auroras over Canada and around the world.
Families will be introduced to the wonders of astronomy through a presentation on a variety of exciting astronomy topics, followed by age-appropriate celestial activities!
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!
