Bulletin

Solar activity has been dominated by minor C-class flares from NOAA ARs 2010 and 2014. These two ARs, and AR 2015, have potential for M-class flares. A rise in the GOES proton levels (10 MeV up to 1 pfu) was seen this morning, this could correspond with the approaching shock of the CME from March 23 (low energy protons and electrons on ACE show an increase at the same time). It could also be related with activity seen at 05:30 UT around NOAA AR 2015, a flare accompanied by dimmings. There is no LASCO data yet but the COR instruments on STEREO show a CME directed towards the west. Geomagnetic conditions are quiet, solar wind speed around 400 km/s, IMF around 5 nT. Conditions may reach minor storm levels with the arrival of the March 23 CME, expected for early March 26 (midnight).

Today's estimated international sunspot number (ISN): 098, based on 16 stations.
