A White Battle in the Black Sea Trillions have died in the Earth's seas. Calcified shields of the dead already make up the white cliffs of Dover. The battle between ball-shaped light-colored single-celled plants -- phytoplankton called...

Astronomical Time Information for
the Fargo-Moorhead Area

Current Local Time:Monday, April 24, 2017 8:22:53 am CDT
Julian Date:2457868.05756
Local Sidereal Time:21:08:07.8

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.
