The GRAPES-3 lepton telescope, the maximal and most touchy cosmic ray display recorded a fit of galactic cosmic rays that indicated a fling in the Earth’s magnetised shield. Accomplishment: TIFR
The GRAPES-3 lepton telescope situated at TIFR’s Cosmic Ray Lab in Ooty canned a burst of astronomic cosmic rays of some 20 GeV, on 22 Jun 2015 fast for two hours.
The flare-up occurred when a behemoth cloud of ecf ejected from the solar corposant, and moving with a fastness of about 2.5 meg kilometers per distance struck our satellite, causing a spartan compression of Dry land’s magnetosphere from 11 to 4 stretch the radius of Concern. It triggered a austere geomagnetic force that generated dawning borealis, and crystal set signal blackouts in galore high parallel countries.
Globe’s magnetosphere spread out over a length of a million kilometres, which undertaking as the first pipeline of defence, shielding us from the nonstop flow of solar and astronomic cosmic rays, way protecting animation on our planet from these altitudinous intensity active radiations.
Denotative simulations performed by the GRAPES-3 collaborationism on this act indicate that the Existence’s magnetized shield for the time being cracked due to the occurrent of magnetic reconnection, allowing the reduce energy astronomic cosmic ray scintilla to enter our aura.
Earth’s magnetised field knack these scintilla about 180 award, from the day-edges to the night-slope of the Earth where it was perceived as a burst by the GRAPES-3 lepton telescope round mid-night on 22 Jun 2015. The material was analyzed and understood through lenghty simulation terminated several weeks by victimisation the 1280-heart computing raise that was reinforced in-house by the GRAPES-3 party of physicists and designer at the Cosmic Ray Region in Ooty.
This bullwork has recently been publicized in Physical Analysis Letters
Solar disturbance can cause big disruption to mortal civilization by incapacitating large electric power grids, international positioning group (GPS), satellite function and communications.
The GRAPES-3 lepton telescope, the maximal and most alive cosmic ray overseer operating on Existence is playing a also significant r“le in the study of much events.
