Title:
First Burst Event Observations of MUSER
Abstract:
The Chinese Spectral Radioheliograph (CSRH) with two arrays in 400 MHz–
2 GHz /2–15 GHz ranges with 64/520 frequency channels have been established
in Mingantu Observing Station, Inner Mongolia of China and is in test
observations now. CSRH is renamed as MUSER (Mingantu Ultrawide SpEctral
Radioheliograph) after it's accomplishment. MUSER has registered several solar
radio bursts events during its commission observations. On 11 Nov 2014, the
first burst event was registered by MUSER-I array at 400 MHz–2 GHz
waveband. According to SGD event list there was a C-class flare peaked at
04:49 UT in the disk center and the radio bursts around 04:22–04:24 UT was
attributed to this flare. However, MUSER-I image observation of the burst
indicates that the radio burst peaked around 04:22 UT was due to the eruption at
the east limb of the Sun and connected to a CME appeared in that direction
about 1 hour later. The possible connections of this radio source to other related
phenomena are also discussed. This demonstrates the importance of the
spectroscopy observation of the solar radio burst.
