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...
