Bulletin

One C-class flare in past 24h: C3.3 from NOAA AR 2519, peak at 12:50 UT on March 9. Most probably associated with a CME (no coronagraph images yet), that will not be Earth directed because it occurred while the AR was rotating over the east limb. More C-class flares can be expected with small chances of an M-class flare from this region. Geomagnetic conditions have been quiet. The solar wind speed is at 350 km/s with interplanetary magnetic field magnitude of 6 nT. A high speed solar wind stream from a small coronal hole may arrive to the Earth within 48h, causing isolated active periods.

Today's estimated international sunspot number (ISN): 069, based on 18 stations.
