“There’s a full moon risin’. Let’s go dancin’ in the light. We know where the music’s playin’. Let’s go out and feel the night.” –Neil Young, Harvest Moon

Join Fairmount Park Conservancy and astronomer/educator Buddy Muhler for a two-mile guided moonwalk and telescope observation on September 26 from 7–9 PM. September’s full moon is known as the Harvest Moon because it’s the closest to the fall equinox and offers extra hours of light for farmers harvesting their summer crops. The Harvest Moon holds major cultural significance in many different communities who spend this full moon not just celebrating the fall harvest but also the moon itself. Native American tribes named it the Big Moon or Corn Moon.

First, we’ll use the moonlight to guide us on a short hike on the Lemon Hill Rim Trail, appreciating nature lit by the glowing moon. Next, we’ll turn our attention to the moon itself. Novice and experienced astronomers alike will be given insights and tips by instructor Buddy Muhler. Each attendee will have the chance to travel close up to the moon’s surface by looking through Buddy’s high-powered telescope! Buddy will discuss the lunar cycles and point out interesting visible surface features such as dark gray mares (seas) and white reflective highlands. We’ll gaze at planets and discuss other astronomical wonders of the night sky.

If you’re a lunar lunatic, this is an evening not to miss!
