Detection of high frequency type iii bursts from ground spectrometers
Answers
The E-CALLISTO (Compact Astronomical Low Cost Frequency Instrument for Spectroscopy and Transportable Observatory) network is a worldwide system in order to observe the Sun's activity in the radio region. At present, more than 80 instruments have been installed at more than 43 locations, with users from more than 113 countries in the e- CALLISTO network. At present, more than 80 instruments have been installed at more than 43 locations, with users from more than 113 countries in the e-CALLISTO network. In this paper, we make use of the e-CALLISTO data that shows a sign of solar activity. On 9th May, the Solar Radio Burst Type III (SRBT III) happens for two times. The first detection of SRBT III occurred less than 1 minute within 05:31UT and 05:32 UT as illustrated in Figure 3. The second SRBT III seems to be occurred within 05:41 UT to 05:42 UT for approximately 1 minute. The Coronal mass ejection which was ejected from the active region AR2339, was detected at 05:42UT has the 'beta-gamma' magnetic field that harbors energy for strong solar flares. From the results, the point we wish to make here is that at least some of these type III bursts with low starting frequencies are consistent with front-side flares, which indicates to us that the low starting frequencies observed for many of these bursts are intrinsic to the type III emissions and do not result from occulting of the high-frequency emissions from any plasma structures.
