Bulletin

Flaring activity remains at low level. A C3.4 flare peaked at 05:23 UT in NOAA AR 1734 (Cat 59). More C-class flaring can be expected in the coming days, with a slight chance for an M-flare. Two filament eruptions are visible in AIA 304 data around 05:20 UT, one to the north and one to the south. Several CMEs were observed in coronagraph data, but none are earth- directed. Geomagnetic conditions remain quiet. The solar wind speed remains elevated (around 500 km/s) due to the influence of a coronal hole.

Today's estimated international sunspot number (ISN): 078, based on 11 stations.
