Welcome

The Radio Astronomy Association Switzerland (RAAS) is a working group of the Swiss Astronomical Society. The members are engaged in the detection and the recording of electromagnetic radiation from celestial bodies, objects and from outer space.

Join our group! New observers are welcome at any time!

December 07, 2020:   The observing station MUHEN of Peter Hirt recorded a 24h-scan of the Milky Way at wavelength 21 cm (Neutral Hydrogen). Therefore, the antenna was fixed and directed to azimt 270° / elevation +70°.
Download the description of the scan for detailled information.
     
November 29, 2020:   The observing station MUHEN of Peter Hirt implemented a self-made Radio receiver designed for the observation of Neutral Hydrogen at wavelength 21cm.
See the Scan of the Galactic plane, showing the radial velocities.
     
October 15, 2020:   The observing station VALLENSIS of Robert Glaisen installed a Cosmic Particles Detector. Follow the links for daily and archive data.
     
July 19, 2020:   Welcome to the new station: The observing station FREIENBACH (FRE) is operated by Christian Monstein. His self-made equipment is designed for the observation of Neutral Hydrogen at wavelength 21cm.
     
June 01, 2020:   The observing station VALLENSIS of Robert Glaisen installed a Meteor Scatter Receiver. Follow the links for daily and archive data.
     
May, 07-09, 2020:   The observing station VALLENSIS of Robert Glaisen recorded a strange temporary increase of the radioactive radiation during about 15-17 UT of each of these days. Other stations didn't record similar effects. The cause of this phenomenon is still unknown.
     
April 28, 2020:   The observing station MUHEN of Peter Hirt implemented a live access to the LDPA radio spectrometer, showing the activity in the range of 45-870 MHz during the last 15 minutes (if active).
     
April 15, 2020:   The observing station MUHEN of Peter Hirt installed a LPDA (Logarithmic-Periodic Dipol Array). The new device is also part of the e-Callisto network. For detailed information please visit Equipment and Recordings.
     
December, 2019:   The observing station VALLENSIS of Robert Glaisen installed a Geiger-Müller counter, type EMD 1.2 (1970). For daily and archived data, please follow the recordings.
     
November 24, 2019:   The observing station MUHEN of Peter Hirt installed a Geiger-Müller counter, type SBM-20. For daily and statistical data, please follow the recordings.
     
August 1, 2019:   The observing station MUHEN of Peter Hirt installed a Geiger-Müller counter, type EMB3. For daily and statistical data, please follow the recordings.
     
April 20, 2019:   The station SWISS-MUHEN recorded the first burst of type 6.
     
April 14, 2019:   Welcome to the new station: The observing station VALLENSIS is located in Brig and is operated by Robert Glaisen. The equipment is designed for the recording of Sudden Ionospheric Disturbances (SID).
     
March 9, 2019:   The station SWISS-MUHEN recorded the first burst of type 2.
     
Jan. 29, 2019:   The station SWISS-MUHEN recorded the first burst of type 1.
     
Sept. 29, 2018:   New location: The antenna and the electronic components of the station swiss-muhen were moved to their definitive position: On the roof of the car port. The situation concerning the receive of noisy signals remained mostly unchanged, according the screenshot of the two polarizations Callisto 01 (upper part) and Callisto 02 (lower part). The station runs stable. As a result of the currently very low activity of the sun, there are no bursts expected for the moment.
     
Aug. 9, 2018:   The station SWISS-MUHEN recorded the first burst of type 3.
     
Aug. 5, 2018:   New link: The website SolarMonitor shows a complete overview of the activity of the Sun. The monitor contains the current data from numerous instruments (SDO, HMI, GHN, SWAP, AIA, XRT) as well as onto the far side of the Sun. Additional diagrams for the fluxes of protons, electrons, x-rays, plasma and B-field (GOES, ACE) complete the activity overview. Beside of this, the monitor allows the view back in history as well as near predictions. Very useful!
     
July 17, 2018:   The Solar Radio Spectrometer of Peter Hirt was connected to the international e-Callisto Network. The station is called SWISS-MUHEN and delivers the data directly to the network server of FHNW.
Introduction and Equipment of the new station.
Congratulations to this great work!
     
Oct. 8, 2017:   "3 - 2 - 1 - lift off" for the new working group! Let's listen to the sky!
