Öffentliche Sonnenbeobachtungen

In the organizer's words:

When the sun shines, the planetarium offers a new highlight during the NRW summer vacations: On Tuesdays and Thursdays, solar observations are offered between 1 and 3 pm.

The observations are suitable for all age groups and families and are accompanied by a member of the planetarium staff.

The explanations of our experts make the observations even more exciting.

The sun is shown in white light and in H-alpha light.

In white light, you can see the sun as you would normally see it with your own eyes.

The surface of the sun and the glowing sunspots can be observed particularly well here.

A filter protects your eyes and the telescope from the strong solar radiation and you can look at the sun without danger.

In H - alpha light, a very unique view of the sun is possible.

Thanks to a special filter that only allows a very narrow area of sunlight to pass through, fascinating prominences, solar flares and exciting structures on the surface of the sun can be observed.

These are invisible in normal light.

The telescope allows you to immerse yourself in the hidden world of the sun.

Come along and experience our home star with your whole family in a new, fascinating and safe way.

When: 15.07.2025-26.08.2025, Tuesdays and Thursdays between 1 and 3 pm. Observation is only possible when the sun is shining.

Admission: The offer is included in the regular museum and planetarium admission.
