Millennium Square Public Star Party - Summer Solstice 2025

Join us on the evening of the Summer Solstice for free public stargazing along the north shore of Lake Ontario, at Millennium Square in Pickering. For the first two hours, we will have a number of solar telescopes showing the active sunspot regions on the Sun, and prominences leaping from the Sun's surface! An hour after sunset, we will enjoy two hours of deepening twilight and night to explore deep space targets in the Summer Milky Way rising over the lake *without moon interference!* (the moon won't rise until after midnight).
Everything gets underway at 7:00 pm with solar-filtered telescopes providing views of sunspots and prominences with our Sun at maximum activity!

Please check our website for a GO/NO-GO decision based on the weather before heading to the Square.

Please note that we make our GO/NO-GO call a few hours before the event, but if the weather worsens, we may have to cancel or wrap up earlier than planned. We'll try to post updates but please use your best judgment if you're planning to join us.
