Bulletin

Solar activity in past 24h has been low. Only minor C-class flaring observed. NOAA AR 2263, produced the strongest one, a C1.2 flare with peak at 20:52 UT. NOAA AR 2268 has potential for larger flares but has been quiet lately. A slow partial halo CME was seen at 15:48 UT on January 24 from a filament eruption close to disk center. Although the eruption is mostly directed to the south, a part of it may hit the Earth on January 29. Due to the southward direction and the low speed, this CME is not expected to be highly geoeffective. Geomagnetic conditions are quiet. The fast speed stream from another high latitude coronal hole may influence the Earth today, although its effect may have missed the Earth due to its location far from the ecliptic plane.

Today's estimated international sunspot number (ISN): 043, based on 10 stations.
