It's that time again. This year's maximum of the Perseids will take place on the night of August 12-13. The highest rate of up to 100 shooting stars per hour is expected towards the morning of the 13th.

Provided the night sky is clear, we open our observatory from 9 pm. Under expert guidance and explanation, we offer a view through our telescope of the objects and the beauty of the summer night sky after dark.

Regardless of the weather, a lecture by Dr. Rolf-Dieter Schad, Zweibrücken Observatory, will take place at 8 pm in lecture hall N101 in the chapel (first traffic circle on campus coming from the city center, on the right). Topic: Our universe

Universe I - Our solar system, of course with consideration of the meteor streams, especially the Perseids.

For personal observation of the Perseids on the green areas around the observatory, we recommend a sleeping mat or blanket and appropriate clothing for the cooler nights. Binoculars are also recommended for a visual walk across the sky.

More information about the Perseids can be found in the sky forecast for the august.


Tour of Germany - RAMOTS visits the Zweibrücken Observatory

The youth group of the Astronomische Vereinigung Bodensee e.V., called "Bodenseesternwarte", has built Europe's largest mobile tracking system for moving celestial and terrestrial objects, called RAMOTS, with around 25 young people.

RAMOTS stands for "Realtime Automatic Moving Object Tracking System". This is a large telescope mounted on a trailer. The telescope can be controlled using a joystick and Arduino microcomputers. This makes it possible to take photos and video recordings of fast-moving objects.

The project was launched in the summer of 2020 in a race to see who could take a good photo of the International Space Station (ISS) first. The solar-powered telescope system can also be used to photograph sailing boats, airplanes, light aircraft, ski racers and much more.

On 22.05.2023 from 4 pm, four members of the "Bodensee-Sternwarte" will demonstrate RAMOTS to the group at the NAWI Observatory Zweibrücken, Amerikastraße 1 (assuming good weather).

In the evening at 8 p.m., the lecture by

Markus Kohler, Bodenseesternwarte
RAMOTS - Hunting satellites with a joystick and telescope

in lecture hall H003 opposite the observatory.

The screening and lecture are open to the public.

The Astronomische Vereinigung Bodensee e.V. (Lake Constance Astronomical Association) was founded in 1996 on the initiative of astronomy enthusiasts whose aim was to educate the public about astronomy. The non-profit association, which is now based in Friedrichshafen, operates a mobile observatory where, depending on the weather, the public can also observe the sky through the association's telescopes.

Participation of the observatory in Open Campus 2023

The Zweibrücken Observatory will be taking part in the Zweibrücken Campus Open Day on 22.04.2023.

We open our observatory from 10:00 to 15:00 and offer our visitors an insight into the world of astronomy. We not only explain how our telescopes work, but also the technology behind them. In addition, our guests have the opportunity to observe the sun in a safe and expert manner.

The following lectures are offered in room H003 (entrance directly at the small parking lot below the observatory):

14:00 Lecture Dr. Walter Arnold

Topic: What can be observed with the all-sky camera at Zweibrücken Observatory?
With the all-sky cameras, an international network of cameras operated by amateur observatories and whose images are publicly accessible, it is possible to observe the burning up of meteroids as meteors ("shooting stars") in the Earth's atmosphere. The lecturer will explain how to access the images from the cameras via the Internet, discuss the origin of the meteroids, their composition and their physical characteristics.

14:30 Lecture Dr. Rolf-Dieter Schad

Topic: Solar observation - carried out as safely as possible
The lecture briefly explains the processes on the sun and shows various methods of observation. Possible dangers are discussed, as the speaker is an ophthalmologist. Some solar eclipses and transits observed by Zweibrücken itself will be presented.


Astronomy Day

Since the International Year of Astronomy in 2009, NAWI has been participating regularly in the activities of the Astronomy Day


Open Campus

We are also taking part in the yearly “Open Campus Day“ of the Zweibrücken University of Applied Sciences, provided weather conditions allow the opening of the observatory. We then explain the principle of the operation of the telescopes and we also offer:

- Observations of the sun with its spots, granules, and prominences with our H-alpha telescope and other telescopes.
- Observations of planets and even stars during daytime if conditions permit.
