Overview
This observation was made in C configuration (max baseline length 3 km) with 26 antenna) in L band (1-2 GHz), with 1 MHz frequency resolution and 1 second time resolution. Two B-class microflares were covered: A B3.6 microflare at 19:59 and a B4.0 microflare at 20:50. RHESSI data is available for both.
