SOLAR RADIO EMISSION MEASUREMENTS

The Solar Astrophysics Group of the Trieste Astronomical Observatory manages a solar multichannel radio polarimeter provided with a parabolic antenna with a 10 m diameter, which operates at a high temporal resolution in a frequency band ranging from 200 to 800 MHz. This instrument, which is located at the O.A.T. branch of Basovizza, permits an in-depth and detailed study of the temporal evolution of radio phenomena. Valuable information can be thus obtained on the processes of plasma occurring at the source, in the solar corona, which proves essential for a better understanding of chromospheric flares physics. Shortly, a second solar multichannel radio polarimeter with a 3 m parabolic antenna will complement the existing instrument, thereby extending the operative range to a frequency band of 1-3 GHz.

In the following we present quicklook data for selected frequencies on a daily basis.

Interested people can request high time resolution data to: Astronomical Observatory, Solar Astrophysics Group, Basovizza 302, 34012 TRIESTE, ITALY.

Please notice that:

• PLEASE NOTICE THAT THE SERVICE IS SUSPENDED UNTIL FURTHER NOTICE DUE TO MECHANICAL AND ELECTRONIC MAINTENANCE OF THE SYSTEM.
• This service is still experimental and we cannot guarantee a daily updating yet.
• Due to strong man-made interferences also at protected frequencies, we show only the two frequency channels that are less interferred.
• We are re-engineering the whole digital acquisition system to serve both the dm and the new cm radio polarimeters, so that quicklook data are temporarily uncalibrated.
