Abstract: Data on disturbed sun emission at different microwave frequencies observed at Saga nore Hill Solar Radio Observatory for a period of about 4 years have been examined in relation to their occurrences, peak flux values, energy excesses and spectral distributions. Important results obtained from the statistical analyses are: (i) spectrum of the average S-component shows a maximum at 4995 MHz and is independent of the phase of the 27-day cycle, (ii) occurrences of both the 'simple' bursts ('simple impulsive' and 'gradual rise and fall) are maximum at 4995 MHz, and (iii) spectra of majority of the 'inverted Uā€™ type of microwave bursts have the peak at 4995 MHz The analysis suggests that for the study of solar terrestrial phenomena the solar flux observation at 4995 MHz would serve as a better index instead of at 2800 MHz assumed till now to be a reliable index.
