dc.description.abstract	Simultaneous microwave bursts were observed at 2.8 and 19.3 GHz at Ahmedabad and at 10 GHz at Hyderabad on 1980 June 4. The peak of the burst occurred at 0836, 0838 and 0840 UT at 19.3, 10 and 2.8 GHz respectively, showing progressive delay from high to low frequencies. Following the theoretical work on magneto-ionic conditions for emission and energetics of electrons during solar flares we estimate the magnetic field to be ~900 gauss, energy of the electrons to be 1.4 MeV and angular size of the burst source to be ~8 arcsec. The brightness temperature of the source was 1.2X10(power 4) K at 19.3 GHz and 2X10(power 6) K at 2.8 GHZ as a result of plasma heating in association with x-ray events.	en
