When the Sky Glows: How the Northern Lights Work (This event is the backup of the same topic cancelled due to hazardous cold weather on Jan 23rd)

Auroras have inspired myths and scientific inquiry across various cultures and throughout history. In this talk, we will explore the interactions between solar activity, Earth’s magnetic field, atmospheric chemistry, and human perception that create these stunning light displays. The colors and visibility of auroras depend on altitude, atmospheric composition, and the tools used by observers. Modern technology enables us to predict, study, and observe auroras in greater detail, benefiting both scientific understanding and our personal enjoyment. Presented by Randy Hemann.

Weather permitting, public sky observing will follow, featuring the young Moon – 8.0 days after New Moon, planets Jupiter, Saturn, Uranus, Neptune, bright stars, double stars, and more by telescope with guidance from members of the Rochester Astronomy Club.
