Bülletään

Solar activity was at low levels during the period. The strongest event was a B1.4 flare peaking at 19:45 UT yesterday. This flare was produced by NOAA 2650 (McIntosh: Cao; Mag.Type: Beta). No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery. The greater than 10MeV proton flux was at nominal levels. B-class flaring is expected, with a small chance on an isolated C-class flare. Solar wind speed increased from about 420 km/s to values around 490 km/s (00UT, 12/04), but then decreased again till 450 km/s. The total interplanetary magnetic field (IMF) strength, as recorded by the DSCOVR satellite, has been around 5 nT. Bz fluctuated between -4.5 and +4 nT, being mostly negative. Solar wind parameters are expected to decline further today. The geomagnetic field was at quiet to unsettled levels, Kp NOAA index: 2-3, local K Dourbes index: 1-3. Quiet to unsettled conditions are expected, with a chance on an active episode.
