AstroEvent: Sonnenbeobachtung zum Tag der Astronomie

Visit us between 3:00 p.m. and 5:00 p.m. on the viadalat and experience a triple solar observation:

Visually through the telescope with an appropriate filter to reduce the intensity of the light.
Through a specially cooled H-alpha filter also on a telescope: H-alpha is a deep red visible spectral line of hydrogen at 656.28 nm, which is crucial in astronomy for the observation of the solar chromosphere.
Through a spectroscope, which converts the data into images that we can view digitally.

Patrick Fricker has been dealing with solar spectroscopy for many years and demonstrates this special type of solar observation on site.

In the course of the evening, you can expect further highlights of the Day of Astronomy:
At 8:30 p.m., the lecture by Dr. Felix Seidel Caprez with exciting insights into modern Earth observation via satellites, drones, ground sensors and artificial intelligence
From 10.00 p.m. observation of the current starry sky with the special light-shadow phenomenon The golden handle on the moon: The peaks of the Jura Mountains are already illuminated by the sun, while the deep plain of Rainbow Bay is still in shadow.

Come by and visit us. We are looking forward to exciting inputs and discoveries with you on this day.
