SOLAR RADIO-BURST (TYPE-III)

This article describes the observations of a type III radio burst obse rved at 103 MHz simultaneously by the two radio telescopes situated at Rajkot (22.3 degrees N, 70.7 degrees E) and Thaltej (23 degrees N, 72 .4 degrees E). This event occurred on September 30, 1993 at about 0430 UT and lasted for only half a minute. The event consisted of several sharp spikes in a group. The rise and fall time of these are comparabl e, however the peaks of individual spikes varied by a factor of four. The comparison of these observations with the data of solar radio spec trograph HiRAS indicates that this was a metric radio burst giving hig hest emission at about 103 MHz.
