Bulletin

Solar activity is low, without C-class flares reported. The strongest reported flare in last 24 hours was the B4.2 flare (peaked at 20:09 UT on January 16) from the Catania sunspot group 7 (NOAA AR 2480). The C-class flares are still possible but not very probable in the coming hours (probability < 30%). No Earth directed CMEs were observed in the last 24 hours. The Earth is inside the slow solar wind with the speed of about 350 km/s. The interplanetary magnetic field magnitude is fluctuating between 4 and 8 nT. The arrival of the halo CME, associated with the filament eruption on January 14, which is expected at the Earth late on January 18 or in the morning of January 19, might induce unsettled to active geomagnetic conditions. We expect quiet geomagnetic conditions in the coming hours.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 057, basierend auf 17 Stationen.
