| Abstract: | Apart from diurnal and seasonal variations, integrated field intensity of
sferics (IFIS) exhibits characteristic variations in relation to various
geophysical and solar events like geomagnetic storms, meteor showers, solar
X-ray flares and solar radio emission. Continuous monitoring of IFIS at frequencies
1, 3, 6, 9 and 12 kHz from Agartala (latitude 23ºN) are being made over the
last several years. The analyses of some preliminary observations in relation
to solar flares are reported in the paper. Solar flare effects on the
propagation of transmitted signals at 16.3 kHz recorded in Kolkata (latitude
22.56ºN) during November 2004 have also been presented |
