Bülletään

During the last 24 hours several C-class flares were reported. Majority of the flaring activity originates from NOAA AR 3030 and NOAA AR 3031 (Catania sunspot groups 45 and 44, respectively). The NOAA AR 3031 still has beta-gamma configuration of its photospheric magnetic field and is, together with NOAA AR 3030 expected to be the source of the C-class and possibly isolated M-class flares in the coming hours. The observations do not show the Earth-directed CMEs during last 48 hours.

The greater than 10 MeV proton flux was at background levels, and the greater than 2 MeV electron flux was under the 1000 pfu threshold, and we xpect them to remain on these levels in the coming hours. The 24h electron fluence is at normal level and we expect it will stay so in the coming 24 hours.

The solar wind velocity has gradually increased during last 24 hours and it presently amounts about 600 km/s. The interplanetary magnetic field magnitude remains to be about 6 nT. The increased solar wind velocity and longer duration interval of the negative Bz component of the interplanetary magnetic field induced active geomagnetic conditions around midnight of June 16. The geomagnetic conditions are presently quiet to unsettled and we expect them to stay so in the coming hours.
