Abstract

Solar radio bursts (SRBs) are the signatures of various phenomena that happen in the solar corona and interplanetary medium (IPM). In this article, we have studied the occurrence of Type III bursts and their association with the Sunspot number. This study confirms that the occurrence of Type III bursts correlates well with the Sunspot number. Further, using the data obtained using the e-CALLISTO network, we have investigated the drift rates of isolated Type III bursts and the duration of the group of Type III bursts. Since Type II, Type III, and Type IV bursts are signatures of solar flares and/or CMEs, we can use the radio observations to predict space weather hazards. In this article, we have discussed two events that have caused near-Earth radio blackouts. Since e-CALLISTO comprises more than 152 stations at different longitudes, we can use it to monitor the radio emissions from the solar corona 24 hours a day. Such observations play a crucial role in monitoring and predicting space weather hazards within a few minutes to hours of time.
