September 8th, Nighty Night, Sol...

For the end of September 6th and most of the 7th, the solar activity was low. Active Regions 1560 and 1562 (AR 1560 and AR 1562) each produced a few low-level C-class flares. AR 1562 continued to grow in area. AR 1567 was designated on the 7th. Its a simple Bxo-beta type spot group. All other regions on the sun's disc were quiet and stable. And no Earth-directed coronal mass ejections (CMEs) were observed. The forecast through September 10th: The solar activity is expected to be low with a slight chance for isolated M-class flare activity.

At home, the geomagnetic field was mostly quiet. The forecast through September 10th: The geomagnetic field is expected to remain mostly quiet. Stay tuned...
