Cancellation Policy

We aim to provide cancellation notices as early as possible. However, weather can be unpredictable, and forecasts aren’t always accurate. Because of this, we typically make our final decision about canceling a program at least two hours before it begins. 

To see whether a program has been cancelled, check our Public Events Calendar, any cancelled program will be clearly marked CANCELLED in the title. You can also look for updates on our Facebook page or call (218) 403‑1345 for the latest information. The most reliable and up‑to‑date source, however, is always our event calendar. 

Weather in our region can be unpredictable, and forecasts aren’t always reliable. While our knowledge of local patterns helps, we evaluate each program carefully based on several conditions:

Program Type  

Some programs require clear skies, especially when we’re viewing faint deep‑sky objects. Others, like observing the Moon or bright planets, can tolerate less‑than‑perfect conditions. The type of program heavily influences our decision.

Wind  

Wind affects both comfort and equipment. Larger telescopes are more difficult to operate safely in strong winds. As a general guideline, we cancel programs when sustained winds reach around 15–18 mph, depending on gusts and the equipment in use.

Cloud Cover  

Clouds are the nemesis of stargazing. If a program depends on sky visibility, we typically cancel when cloud cover reaches 50–70%.

Smoke  

Wildfire smoke impacts both health and visibility. If the Air Quality Index (AQI) is 110 or higher two hours before the program, we will cancel for safety and viewing quality.

A Combination of Conditions  

Cancellations are rarely based on a single factor. More often, it’s a combination of conditions that would create an unenjoyable or unproductive experience. While we truly dislike canceling programs, and do everything we can to avoid it, sometimes it’s necessary to ensure safety, protect equipment, and provide a quality experience. Our goal is always to offer the best possible introduction to astronomy. Poor conditions can leave a negative impression, and we want every visitor to walk away excited about the night sky, not disappointed by it.
