Bulletin

Solar activity was eruptive with several C flares and is expected to remain that way for the next 24 hours. A rise in the proton levels was detected, but still below 10 000/(cm2 s sr). The levels are, however, still rising, especially for the 10 MeV. A very small jump in the solar wind and a turbulent interplanetary magnetic field indicate the arrival of the CME detected by LASCO C2 on March 12th 11:00 UT. The geomagnetic condition remained quiet to moderate, but are expected to reach Active to Storm levels on Monday, March 18th around 13:00 UT with the arrival of the full halo CME of March 15th 7:12 UT.

Today's estimated international sunspot number (ISN): 078, based on 07 stations.
