Stargazing with Don Jolley
A monthly stargazing event will, weather permitting, occur the week before each new moon. The event supports the preservation of our nightscape.
Join astronomy teacher and storyteller extraordinaire Don Jolley before each
new moon to learn the names of planets, stars, and constellations and hear spellbinding stories about billions and billions of celestial bodies.
Look on the right side of this page or scroll down on your phone for a description of upcoming stargazings and for Don’s weather reports.
