Microwave observations with the Siberian Radioheliograph

Alexey Kochanov, Institute of Solar-Terrestrial Physics of SB RAS

The Siberian Radioheliograph (SRH) is a new multi-frequency interferometer located in the radio-quiet Badary area, 220 km southwest from Irkutsk, Russia. The SRH has a T-shaped 48-antenna array with a longest baseline of 107.4 m and routinely observes the Sun in the 4–8 GHz frequency range. We focus on our activities in the SRH data processing, including calibration methods and image-synthesis algorithms. We demonstrate SRH capabilities to trace the evolution of various solar phenomena in the microwave range by using examples of some eruptive events detected.
