SolarHam.com | Solar Update - Tuesday morning 10-4-11

A long duration C7.3 Solar Flare took place around Sunspot 1302 at 09:23 UTC Tuesday morning. This region is now rotating onto the western limb and any explosions at this point will not be earth directed.

An aurora watch will be in effect within the next 24-48 hours due to the expected arrival of a Coronal Mass Ejection (CME) caused by a long duration M1.2 solar flare around Sunspot 1305 on Saturday morning. Minor geomagnetic storming may be possible at high latitudes.

Two new sunspots formed on Monday in the southern hemisphere, and one of them was numbered 1310. At the same time, another sunspot rotated into view on the northeast limb. Sunspot 1308 has faded away.
