Moderate solar flare reaching M3.3 peaked at 17:55 UTC on Sunday, June 3, 2012. The quick flash of light was centered around Sunspot 1493 located in the northern hemisphere. A TenFlare measuring 320pfu was recorded as well.

A Type II emission (est 1077 km/s) was also reported at at 17:59. A CME was later observed in LASCO C3 imagery departing the northeast limb at
18:54. Earlier in the day, C3 imagery showed a CME departing the southeast limb at 13:42 associated with a filament eruption.

A minor Geomagnetic Storm (KP=5) is now in progress due to a southward Bz component of the IMF. Be on the lookout for Aurora at high latitudes.

New Region 1499 (N16E50) was numbered today as a small Dso type group with beta magnetic characteristics. All regions on the disk today were classified as simple alpha or beta magnetic characteristics.



The Bz component of the Interplanetary Magnetic Field has been tilting sharply south for long durations and this has in turn generated a G1 Level Geomagnetic Storm at very high latitudes. Furthermore, a Geomagnetic Sudden Impulse was detected very early this morning.
