Open Observatory Day: Observing the sun

Free solar observation

Observing the sun through a telescope

Visit the observatory on five selected dates throughout the year, funded by Migros Kulturprozent. Experience solar observation on two Sundays from 1:00 PM to 4:00 PM during the summer and explore the fascinating world of stars through our telescope on two Saturday evenings from 7:30 PM to 10:30 PM during the winter.

On various days, you can observe the sun through a telescope on Gurten and gain exciting insights into our solar system. The event is weather-dependent and will be rescheduled or canceled in unfavorable conditions. Sign up on the list to be informed about any changes before the event. The final decision on the event's execution will be announced on our website two days in advance.

Attention: Never observe the sun without suitable protective glasses or equipment, as this can cause serious eye damage. On Gurten, you will receive the necessary instructions and materials for safe observation.
