Abstract |
|
The structure of the heliosphere controls by solar outputs and their variability produces changes in cosmic ray intensity on long-term and short-term basis. Based on the observation from Omniweb data centre for solar- interplanetary data and monthly mean count rate of cosmic ray intensity (CRI) variation data from neutron monitors were used during 1996-2014. It is observed that during declining phase of solar cycle 23and ascending phase of 24 solar cycle , the sun is remarkably quiet and the strength of the interplanetary magnetic field has been falling off to new low levels , reduces the GCR entering inner- heliosphere and it is high anti-correlation has been found between sunspot number & GCR flux. It is also found that count rate of cosmic ray intensity and solar- interplanetary parameters were inverse correlated and these solar indices were positive correlated. |
