Geomagnetic solar flare effect in the dark hemisphere

Sastri, J. H (National Institute of Science Communication And Information Resources, 1975-09)

Normal run magnetogram data obtained at Huancayo, Kodaikanal and Kakioka show that the geomagnetic solar flare effect (SFE or Crochet) occurs not only in the sunlit hemisphere but also in the dark hemisphere. Using a ...
Nature of crochet associated solar microwave bursts

Sastri, J. H (National Institute of Science Communication and Information Resources, CSIR, 1977-09)

Using crochet data at Kodaikanal and solar-microwave-burst data at Toyokawa, Japan, a study is made of the nature of crochet-associated solar microwave bursts. Consideration of the results in the light of earlier work ...
On the relationships between sfe (crochet) and solar X-ray and microwave bursts

Sastri, J. H; Murthy, B. S (D.Reidel Publishing Co.,, 1975-04)

Geomagnetic crochets (sfe) observed at Kodaikanal over the period 1966-71 have been studied in relation to solar X-ray bursts observed by NRL satellite (SOLRAD-9) in the 0.5-3 A, 1-8 A and 8-20 A bands and radio bursts ...
