Bulletin

The strongest flare during the last 24 hours was an M1.4 flare peaking on 1 July at 11:23UT and originating from filamentary activity between small sunspot regions NOAA 2102 and 2106. Most of the C-class flares also originated from NOAA 2106. NOAA 2104 and 2107 are the largest and magnetically most complex sunspot regions, but produced only one C-class flare each, the strongest a C6.6 peaking at 07:37UT this morning and having its source in NOAA 2107. No coronagraphic images are available yet to evaluate any of the CMEs that may be associated to the recent flaring activity. The other CMEs had their source on the Sun's farside or were directed away from Earth. There's a good chance for further M-class flaring. Solar wind speed hovered around 350 km/s while Bz oscillated between -5 and +5 nT. Quiet geomagnetic conditions were observed and are expected to remain so.

Today's estimated international sunspot number (ISN): 101, based on 18 stations.
