Calvin Observatory

Welcome!

SPECIAL EVENT: Partial Solar Eclipse: Weather permitting we will have special viewing of the sun on October 23 from 5 pm to 6:30. Beginning at 5:39 pm the sun will be partially eclipsed by the moon. For us the degree of eclipse will increase through the time of sunset.

Viewing of the sun's photosphere (visible surface) will be available with our main telescope (fitted with an appropriate filter). Viewing of the sun's chromosphere (upper atmosphere) will be available with our new hydrogen alpha telescope. Viewing begins at 5 to highlight the uneclipsed sun via these special means of viewing.

Fall observatory schedule: The telescope on the roof of the Science Building is open for visitors from the Calvin community clear nights Monday through Thursday. It is also open to the general public on Wednesday nights. There is no charge for admission. It is helpful for large groups to notify us in advance.

The observatory is open from 7:30 to 11 pm EDT.
