"Lunar phenomena have much to offer teachers as both an engaging narrative and visible presence in the sky. International Observe the Moon Night, being held this year on Saturday, September 26th, is a time to honor the educational, cultural, and personal connections to the Moon. Note that this night marks the first-quarter Moon, offering excellent viewing opportunities along the terminator (the line between the light and dark side of the Moon), where shadows enhance the Moon’s cratered landscape."
