More collaborative investigations are in progress.
The scientific output of our VLA observations has greatly enhanced because of the availability of Yohkoh soft and hard X-ray data. We have also found radio signatures of superhot component of a hard X-ray Flare. We are also investigating the X-ray signatures of Coronal Mass Ejections in collaboration with Drs. H. Hudson and N. Nitta. We have started using the Nobeyama Radioheliograph data at 17 GHz in conjunction with Yohkoh data to study Bright Points and Filament Eruptions.
