Ajax's biggest family event of the year comes up on October 18. The Toronto Centre's Durham Region team will be in attendance with tables of crafts for little ghosts and goblins, an information booth, and a number of solar telescopes for safe viewing of the Sun's active sunspots!

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!

Safely observe the sun with us! During these family-friendly sessions, a DDO Astronomer will answer your questions about our closest star: the sun!
