dc.description.abstractSolar X-ray bursts recorded by Explorer 37 satellite in the bands 0·5-3, 1-8 and 8-20 Ǻ have been analyzed in relation to their morphological types and peak time attainment at the different wavelength bands. They have also been examined in relation to (i) solar microwave bursts recorded at different frequencies by Sagamore Hill and Manila solar radio observatories and (ii) sudden ionospheric disturbances recorded all over the globe. It has been found from both statistical analysis and actual time profile of X-ray bursts that they are mainly of three different morphological types, namely, (i) impulsive, (ii) gradual rise and fall (grf) and (iii) gradual rise and quick fall (grqf) in contrast to their earlier classification into two types only. Impulsive X-ray bursts were found to be more associated with bright H-flares and also with different microwave bursts and SIDs, in comparison to those for the 'grf' and 'grqf' types of X-ray bursts. The peak of the X-ray bursts at a shorter wavelength is attained in most of the cases earlier than that at a longer wavelength, in general, and this time separation (+Δt) is more prominent with increasing difference between the bands of the X-rays. X-ray bursts having small Δts are more associated with bright Hɑ.-flares, while bursts with large Δts are found to be more associated with Hɑ.-flares having large durations. It has further been observed that the association of the X-ray bursts, in general, with SIDs in the presence of microwave bursts is about double in comparison to that in the absence of microwave bursts.en_US
