| Abstract: | The present study explores the ionospheric effects of the well cited solar
flare events (M3.2, M3.9/2N) of 18 November 2003 associated with CMEs.
The Hα observations of these flares (taken with 15 cm Solar Tower Telescope at
ARIES, Nainital) have been analysed to see an association of these flare events
with the geomagnetic storm occurred on 20 November 2003. The ionospheric data
from Puerto Rico (18.5°N, 67.2°W), Dyess (32.4°N, 99.7°W) and Millstone Hill
(42.6°N, 71.5°W) together with the disturbance storm time indices (Dst index)
variability exhibited a corresponding associations having a delay in the solar
wind parameters, triggered by these flare events. |
