I have attempted a correlation of low amplitude radio bursts at 3 cm with transient features on Hc~ films. The 130 ft antenna at Owens Valley Radio Observatory has a HPBW of about 3 rain at 3 cm, enabling us to track a single active region which was followed at the same time in He with the 13 cm ph

β¦ Synopsis
Once the area of a thermal burst region has been determined, it is possible to obtain the temperature and emission measure of the burst by examination of the flux spectrum. Such determinations have been made for three events. Temperatures in the range 2 to 6 β’ 106K and emission measures in the area of 2.6 to 5.4 β’ 1049 cm -a are consistent with radio observations. Electron densities are estimated to be of the order of 1 to 5 β’ 101~ electrons cm -8.
