Astronomy 110 Campus Observatory

Check here or call the hotline (575-646-6278) after 8pm on the day of campus observatory to see if it will be open or closed.

Campus Observatory begins August 28th (if you want a chance for a good view of Saturn, come the first two weeks).



You are required to turn in FOUR observation sheets for your observatory notebooks from each of your visits to the observatory. Please bring your own copies of the worksheets.

First half:  August 28, 2017 – October 4, 2017
Second half: October 9, 2017 – November 22, 2017

The Campus Observatory is located on Williams Street just to the south of the parking lots, and just in front of the track. It is set back from the street a bit, so look for three domed buildings. Linked is a more detailed map.

Weather permitting, the observatory is open on Mondays and Wednesdays from 9-10 PM. Please check this page to find out if observatory is open or closed due to cloudy, rainy, dusty or stormy skies (note that we cannot see stars and planets through clouds, and dust damages the optics of our telescopes!). Sometimes it clears too late to open, while other times it will cloud-up right before we open. That’s life in the astronomy world. Thus, it is best to always try to do your observing at the beginning of each observing period, and not wait until the last possible week—you may get clouded out, and there is no way to make-up this work.

If you would like to see the cloud coverage heading our way in the next few hours, or learn about the conditions that might close our 3.5 meter telescope up in Sunspot NM, take a peek at the Apache Point Weather Information Page.
