Talk topic: Comets! Centuries ago, comets were considered harbingers of doom, or at least of very bad news. What are comets, really, and what makes them so interesting? How do they get those weird names?
Talk starts in the AB Ceder room. After the talk there will be stargazing if the weather permits. Free; open to the public. Children under 16 must be accompanied by an adult. Dress warmly, as even in the summer it may be chilly.
