Bulletin

During last 24 hours sixteen C-class flares were reported, majority of them originated from the active region currently on and behind the East solar limb. The strongest flare was the C8.9 flare which peaked at 16:08 UT on January 17. The flare originated from the active region situated just behind the East solar limb and was associated with the CME directed southward from the Sun-Earth line. We expect C-class flares are probably also isolated M-class flare in the following 24 hours. The Earth is inside a slow solar wind with a speed of about 310 km/s. The interplanetary magnetic field is still stable with the magnitude between 2 and 3 nT. The glancing blow from the CME-driven shock wave, associated with the partial halo CME observed on January 14, is expected to arrive at the Earth today. Therefore we expect quiet to unsettled to geomagnetic conditions in the following hours. The CME-driven shock wave, associated with a partial halo CME (limb event) on January 16, could be expected on January 20-21.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 082, basierend auf 13 Stationen.
