Astronomy Talks and Observatory Viewing

FALL 2017

The talks will be held in Centennial Science Hall (CSH) 271 and, if the night is clear, the observatory viewing sessions will be on the 3rd floor deck of CSH. Both are free, open to the public, and suitable for all ages. You can call 715-425-3560 or log onto after 6 pm on the day to see whether the night is clear enough for viewing, but the talk will go on as scheduled.

Contact Eileen Korenic ( for information on pre-observatory talks and Glenn Spiczak ( for observatory information.

Objects to be seen include planets, globular clusters, open clusters, nebulae, galaxies, moons and double stars. The presenter for all three talks will be Eileen Korenic.

Observing Tips | Stargazing Links

The Observatory is on the 3rd floor, Centennial Science Hall (CSH), at the corner of 6th and Cascade. Sessions are free and open to the public. 

If you would like to be on our "stargazers" email distribution list, send an email using the address you wish to subscribe to with the following message body:
SUBSCRIBE stargazers

For observing, use the outside Observatory stairwell near the south door of CSH if/when it is open to avoid disturbing the sky above with light and heat from inside. Otherwise, use the nearby CSH entrance.

If you need assistance or elevator access to the 3rd floor, please let us know (elevator keying is required). Talks are in 271 CSH 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 5 pm and post our decision here to allow for adequate setup time.  We will always plan to present the talk.

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.
