Astronomy Picture of the Day: Comet Hale Bopp Over Val Parola Pass
December 8, 2021

Comet Hale Bopp Over Val Parola Pass Comet Hale-Bopp, the Great Comet of 1997, became much brighter than any surrounding stars. It was seen even over bright city lights. Away from city lights, however, it put on quite a spectacular show....

Astronomical Time Information for
the Fargo-Moorhead Area

Current Local Time:Wednesday, December 8, 2021 7:37:01 pm CST
Julian Date:2459557.56737
Local Sidereal Time:00:23:18.4

The following sunrise/sunset times are for Paul P. Feder Observatory at Buffalo River State Park, about 14 miles from the MSUM Campus. They are only accurate to about 3 minutes since no attempt has been made to deal with the effects of changing temperature/humidity on atmospheric refraction. However, they should be reasonably accurate anywhere in the Fargo-Moorhead area.
