Observatory pictures from an earlier viewing. Objects seen included planets, globular clusters, open clusters, nebulae, galaxies, moons and double stars.




The UWRF Observatory, located on third floor of Centennial Science Hall (south end stairwell), is equipped with a 16-inch Meade computer-controlled LX200GPS mounted under the dome, three portable telescopes (two 12-inch Meade LX200 and one 18-inch Obsession Dobsonian), Coronado SolarMax60 and PST Solar Telescopes. We also have two parallel RadioJOVE telescopes installed on the roof of Rodli Hall across the street, in addition to a number of QuarkNet cosmic ray air shower detectors running at various times throughout the year.

Call 715-425-3560 or log onto after 6 p.m. on the day of the event to see whether the night is expected to be clear enough for viewing.

If you need assistance or elevator access to the third floor, please let us know (elevator keying is required). Talks are in CSH 271 on the opposite side of the building, closest to the north entrance.

Weather Conditions for Viewing:

The sky should be almost completely clear, so look up before you leave home. Generally, we will cancel a session by 6 p.m. and post our decision here to allow for adequate setup time. The talk will go on regardless of the weather.

Our decision is a best guess based on current satellite images and forecasts, but occasionally we are fooled and request your forgiveness. Check this site or call 715-425-3560 for the latest update.
