A local astronomy club is offering another of its free sidewalk science programs as part of a worldwide event this week to promote understanding of the Earth’s moon.
Whatcom Association of Celestial Observers will be at the main entrance to Bellis Fair mall, 1 Bellis Fair Parkway, from 6 to 9 p.m. Saturday, Oct. 8, which is International Observe the Moon Night. They will be on the sidewalk near the entrance at the food court, said WACO member Richard Just.
WACO members will bring different kinds of telescopes with various lenses to show the difference between reflector and refractor models and how the moon appears in detail with high magnification.
The club offers free sky-viewing opportunities in summer at Boulevard Park and Artist Point, as well as events during celestial phenomena such as eclipses. As with all WACO events, it is canceled in the event of cloudy skies.
Digital Access for only $0.99
