Bülletään

Catania sunspot groups 40 and 43 (NOAA ARs 1718 and 1719, respectively) continue to decay although they still have beta-gamma configuration of the photospheric magnetic field. No C-class flares were detected during the past 24 hours. We expect flaring activity on the low C-level, with an M-class flare being unlikely. The Earth is currently inside the magnetic cloud associated with the halo CME observed on the Sun on April 11. The magnetic cloud belongs to the ENW type (left-handed), and therefore does not contain southward interplanetary magnetic field (IMF). Since the arrival of the shock driven by this magnetic cloud late on April 13, the IMF Bz component was steadily positive and the solar wind speed did not exceed 560 km/s, so no geomagnetic storm occurred (K index stayed below 4). Currently the solar wind speed is around 390 km/s and the IMF magnitude is around 9-10 nT. Unless the IMF turns strongly southward, which is unlikely, we expect quiet geomagnetic conditions.
