Unless otherwise noted, all Eagle Lake Observatory public star parties are “all weather” events. 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 website homepage at www.mnastro.org, after 4:00 pm the day of the event for cancellation notices.
