HYPERACTIVE DAY!

THE KP INDEX HAS REACHED 5 and indicates ONSET of Geomagnetic Storm G1

Kp reached 5 at around 0900UTC.Further Storming is expected and G3 Geomagnetic storm probability can't be ruled out.

M6.6 Solar Flare-

At around 1011UTC, Sunspot 1158 released another Solar Flare of X ray flux M6.6 category. Shortly after this release, Moderate Level RADIO BLACKOUT i.e R2 was noticed on the sunlit side of the earth.

The arriving datas from STEREO shall indicate whether Coronal Mass Ejection has been hurled out or now. Being it very strong, I expect a CME and might be directed towards the earth

CME hits the earth !

The Anticipated Coronal Mass ejections from 15th Feb and 13th Feb events have arrived which was detected by series of shocks recorded by the ACE spacecraft

The earth is having a magnetic field. Sun's magnetic field known as Interplanetary magnetic field(IMF). These two fields are in contact at Magnetopause. Earth's magnetic field is directed towards North and if the IMF points South then due to opposite in nature, IMF partly cancels earth's magnetic field at the point of contact. This phenomena is known as "southward B_z"

This results in pouring in of Solar Wind which triggers Auroras.

The Bz index has reached to 30nT meaning passing of shockwave ( 5-6UTC)

Kp index is now unsettled with level 4 and its expected to reach to 5 indicating G1 storm

High latitude observers must remain alert for Auroras.
