AR 1584's C1 Flare on October 2nd...
The above image was taken October 2nd at 09:04:00 UTC by the Atmospheric Imaging Assembly (AIA) aboard the Solar Dynamics Observatory (SDO). This was during the time of a C1 solar flare, produced by Active Region 1584 (AR 1584), in the southeast (lower-left) quadrant. The displayed image combined the AIA observations at 94, 131, and 171 Angstroms. Image Credit: SDO/AIA
For the end of October 1st and most of october 2nd, the solar activity was low. Active Region 1584 (AR 1584) produced the largest event, a C1 solar flare on the 2nd at 09:04 UTC. And a new group, AR 1585 (in the southeast quadrant) was numbered. No Earth directed coronal mass ejections (CMEs) were observed. The forecast through October 5th: The solar activity is expected to range from low to very low.
Here at home, the geomagnetic field was quiet. The forecast through October 5th: The geomagnetic field is expected to be mostly quiet. Stay tuned...
