Astronomy Picture of the Day: Sharpless 308: The Dolphin-Head Nebula
October 21, 2021

Sharpless 308: The Dolphin-Head Nebula Blown by fast winds from a hot, massive star, this cosmic bubble is huge. Cataloged as Sharpless 2-308 it lies some 5,000 light-years away toward the constellation of the Big Dog (Canis Major) and covers...

Astronomical Time Information for
the Fargo-Moorhead Area

Current Local Time:Thursday, October 21, 2021 8:36:23 am CDT
Julian Date:2459509.06693
Local Sidereal Time:09:11:27.4

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.
