August 29th, Snoozy Sol...

The above image was taken August 28th at 03:07:00 UTC by the Atmospheric Imaging Assembly (AIA), at 304 Angstroms, aboard the Solar Dynamics Observatory (SDO). This was the time of the B6-class solar flare produced by Active Region 1558 (AR 1558), on the east limb above the equator. Image Credit: SDO/AIA

For the end of August 27th and most of the 28th, the solar activity was very low. The largest solar flare of the period was a B6 flare, produced by Active Region 1558 (AR 1558) on August 28th at 03:07 UTC. A new region was designated, AR 1559, and no Earth-directed coronal mass ejections (CMEs) were observed. The forecast through the 31st: The solar activity level is expected to range from low to very low, with a slight chance for moderate activity.

At home, the geomagnetic field has been relatively quiet. The forecast through the 31st: The geomagnetic field is expected to be predominately quiet. Stay tuned...
