Solar Storm In Effect - CME Arrived (Updated)


    Update:  Jan 22nd 23:41 UTC
  At this time we are having a G1 Geomagnetic storm.
Geomagnetic conditions are ongoing
So far, conditions peaked between 10:00-12:00 UTC today. Solar winds topped out at speeds over 450km/sec. Density reached  65.6 protons/cm3


Current Solar Conditions:
Wind Speed: 447.9 km/sec
Density: 19.8  protons/cm3

Solar Storm Level - G1 - Minor
Kp Level is now at-  Kp5
High & Mid Latitude Aurora Watch in Effect




CME IMPACT: A coronal mass ejection (CME) hit Earth's magnetic field at 0617 UT on Jan. 22nd. At first the impact did not appear to be a strong one: the solar wind speed barely lifted itself to ~400 km/s when the CME passed by. Now, however, in the wake of the CME, a dense and increasingly geoeffective solar wind stream is blowing around Earth, setting the stage for possible auroras on the night of Jan. 22nd

FROM SIDC - RWC BELGIUM Sun Jan 22 2012, 1242 UT: The Earth is currently downstream of the shock wave that arrived at ACE at 05:15 UT today. The solar wind speed is now around 420 km/s and the interplanetary magnetic field (IMF) magnitude is around 20-25 nT. The north-south IMF component Bz is fluctuating between positive and negative values as the Earth is still situated in the sheath region between the shock and the ICME.
