Onan public star parties are "all weather" events (unless otherwise noted). Even if it is cloudy, someone will be there to show a video, give a presentation, give a tour of the observatory or answer any astronomy questions you may have. However, there may be a need to cancel due to hazardous weather conditions such as severe thunderstorm, tornados and/or snow storms.
If any of these conditions are threatening, please check the MAS homepage
and/or the MAS info line at 952-467-2426, after 4:00 pm the day of the event for cancellation notices.
The full Public Star Party Schedule at the Onan Observatory can be found HERE.
If you are new to public star parties, please review the "Star Party Guidelines"
on the MAS website.
