G1 geomagnetic storm in progress

g1-geomagnetic-storm-in-progress-2

Interplanetary Magnetic Field (Bz) has been pointing south at times today (Monday) and combined with the solar wind at near 500 km/s, it has generated a minor G1 Geomagnetic Storm at high latitudes. Storm levels reached Kp index of 5. The geomagnetic field is expected to be generally unsettled for tonight as effects from the current disturbance persist. Predominantly quiet levels are expected for February 29 February –  March 1.

We can expect nice images of auroras soon.

Minor C-Class activity was detected around  region 1421, with biggest solar flare measuring C2.3 at 21:41 UTC. All of the current visible sunspots remain stable and there is no chance for strong solar flares at this time.

SOHO’s latest LASCO C2 images reveal a coronal mass ejection (CME) seen off the western limb but it looks like it’s not Earth directed.
