Astronomical Time Information for
the Fargo-Moorhead Area

Current Local Time:Tuesday, August 14, 2018 2:07:05 am CDT
Julian Date:2458344.79659
Local Sidereal Time:22:11:55.0

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.
