Observations of successive CMEs and their successive Type II solar radio bursts in the corona.

ABSTRACT: This paper reports the observations of two coronal shocks from two Coronal Mass Ejections (CMEs) for the Successive type II Solar radio bursts observed on 02 May 2021 in the frequency range of 80 - 1 MHz with the time interval of ∼ 20 minutes between them. Both the bursts show clear band splitting features in the harmonic band. The estimated heights for the source of the first type II burst lies in the range of 2.06 - 2.93 [Formula: see text] with the average speeds of 601 ± 76, 700 ± 91 and 783 ± 105 km [Formula: see text] for 2 X, 3.5 X and 5 X Saito electron density models, and the heights for the source of the second type II burst lies in the range of 2.24 - 3.83 [Formula: see text] with the average speeds of 1063 ± 113, 1287 ± 145 and 1478 ± 172 km [Formula: see text].
