Mammatus Clouds over Nebraska When do cloud bottoms appear like bubbles? Normally, cloud bottoms are flat. This is because moist warm air that rises and cools will condense into water droplets at a specific temperature, which usually...

Astronomical Time Information for
the Fargo-Moorhead Area

Current Local Time:Sunday, December 15, 2019 3:09:55 pm CST
Julian Date:2458833.38189
Local Sidereal Time:20:21:02.5

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.
