Bülletään

Solar activity was at very low levels. No flares were observed during the reporting period. CACTUS detected a narrow NW CME from LASCO C2 images around 17:36 UT yesterday. This CME is not expected to be geoeffective. Integral proton flux for protons with energies above 10 MeV remained at background level. B-class flaring is expected.

Solar wind speed fluctuated strongly between 450 km/s to 400 km/s during the period. The interplanetary magnetic field gradually increased from 3 nT to 8 nT. Bz fluctuated between -3 and +3 nT before 00 UT and then gradually decreased to -6 nT. Geomagnetic conditions were ranged K Dourbes between 1 and 3; NOAA Kp between 1 and 4 during the reporting period. A high speed stream from a positive coronal hole (CH HSS) is expected to disturb further the solar wind environment. Active geomagnetic conditions are expected. Isolated episodes of minor storm are possible
