Abstract
We have analyzed fourteen solar impulsive flares simultaneously observed with microwave and X-ray imaging instruments (the Nobeyama Radioheliograph and the Yohkoh X-ray telescopes). All of the events analyzed are short-lived, consisting of a single or multiple spikes with each spike duration of about 10 s and showing quite hard, hard X-ray spectra with relatively small photon counts in the HXT L-band. Hence, we believe that these events reveal most clearly the behavior of energetic electrons without severely contamination by thermal emission from super-hot (~ 30MK) flare plasma.
