ARCAS

ARCAS is a digital spectrometer based on a Software Defined Radio receiver configured to scan the band 45 - 450 MHz. It has been set up on October 27 2016, in parallel to the CALLISTO receiver already in operation. Both instruments share the same receiving antenna via a splitter.

HSRS

HSRS is a digital spectrometer based on a Software Defined Radio receiver configured to scan the band 275 - 1495 MHz. It has been set up in late July 2015. HSRS is connected to a broad-band antenna located at the focal point of the 6-m dish.

SPADE

SPADE is a compact 8 antennas phased array and a digital spectrometer based on Software Defined Radio receivers. It started observing in the fall of 2024. 

Quicklook files

Daily quicklook overview combining ARCAS, HSRS and SXR light curves from GOES are available on this website. The very last 2 hours observations from ARCAS and HSRS and selected light curves from HSRS are also available. FITS files can be requested by email to the contact person. 

SPADE quicklook files are available on this website. The whole series of observations will be soon available. RAW files an be requested by email to the contact person.
