Humain Radioastronomy Station

Royal Observatory of Belgium

Instrumentation

We currently operate one 6-m dish, tracking the Sun automatically from ~7h30 until ~16h00 UT everyday. The dish hosts two antenna, one for the low frequency part of the spectrum, mounted as piggy-bag on the side of the dish, and one for the high frequency part of the spectrum, installed at the focus of the parabolic dish. We do radio spectrography between 45 and 1500 MHz.

Callisto

Callisto is a spectrometer developped by Christian Monstein from ETH Zürich. It can natively cover the band 45 - 870 MHz, and is a programmable device: the Callisto receiver set up in Humain is configured to monitor the band 45-450 MHz, in 200 frequencies, 4 times per second. It has been observing since 2008.

Different Callisto receivers are installed around the world and are part of the e-callisto network. Data from the whole network can be accessed here.

Data from the Callisto receiver in Humain are available by following these links:

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.

Data will be very soon available on this website. FITS files will be available by sending an email to the contact person.

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.

Quicklook data from HSRS can be looked at by following the links below. FITS files can be requested by email to the contact person. The quicklook files show the HSRS spectra combined either with Callisto or ARCAS data, plus SXR light curves provided by the operational GOES satellite:
