Astronomy Picture of the Day: M43: Orion Falls
December 12, 2018

M43: Orion Falls Is there a waterfall in Orion? No, but some of the dust in M43 appears similar to a waterfall on Earth. M43, part of the Orion Molecular Cloud Complex, is the often imaged but rarely mentioned neighbor of the more...

Astronomical Time Information for
the Fargo-Moorhead Area

Current Local Time:Wednesday, December 12, 2018 10:09:54 am CST
Julian Date:2458465.17354
Local Sidereal Time:15:09:19.8

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.

Solar Day (Sun Rising/Setting)8:01 am CST4:37 pm CST
Astronomical Day (Darkest Skies)6:10 am CST6:28 pm CST
