We use broad-band teleseismic data recorded at eight sites along a north-south profile from Karimganj (24.84°N, 92.34°E), south of the eastern Shillong Plateau, to Bomdilla (27.27°N, 92.41°E) in the eastern Lesser Himalaya, ...

Areas and positions of individual sunspot umbrae measured in white-light solar images from Kodaikanal and Mount Wilson are compared and shown to be in quite good agreement. The agreement is sufficiently good that it is ...

First results on the behavior of thermospheric temperature over Kavalur (12.5 deg N, 78.5 deg E geographic; 2.8 deg N geomagnetic latitude) located close to the geomagnetic equator in the Indian zone are presented. The ...

We present group velocity dispersion results from a study of regional fundamental mode Rayleigh waves propagating across the Indian region. 1-D, path-averaged dispersion measurements have been made for 1001 source-receiver ...
