Bulletin

Several C-flares occurred in the past 24 hours. The strongest one was a C3 from NOAA AR 1653 peaking at 03:03 UT. Other flaring regions are 1652, 1650 and 1645. These last two have a beta magnetic configuration, while 1652 and 1653 are still not visible completely (rotating into view from the east limb). NOAA AR 1640 remains the most complex AR, as it's still slowly growing in size and keeps its beta-gamma-delta configuration, this region is approaching the west limb but can still produce M-class flares. Geomagnetic conditions have been quiet. Unsettled to (isolated) active levels can be expected in the next 24h with the arrival of a fast speed stream from a small coronal hole.

Today's estimated international sunspot number (ISN): 108, based on 03 stations.
