Solar Eclipse in Bozeman MT on 21-Aug-2017

A total solar eclipse is expected to be observed by thousands of people in the United States on August 21st, 2017. I'm sure many folks have a plan to fly or drive somewhere to watch this spectacular event. Unfortunately, Bozeman is located slightly outside the path of totality. This means that the Sun will not be totally covered by the Moon. However, about 95% of its area will be covered and only leave a thin crescent Sun. It is such a rare event that you should not miss this amazing phenomenon.

This page is dedicated to those folks who observe this eclipse in Bozeman!

Most importantly ...

Observe it Safely!
