Bulletin

The strongest, out of few C-class flares reported during last 24 hours, was the C1.7 flare (peaking at 15:25 UT) on January 15. We expect C-class flares in the coming hours, in particular from Catania sunspot group 7 (NOAA AR 2480) which was source of the majority of flaring activity during the last 36 hours. No Earth directed CMEs were observed in the last 24 hours. The solar wind speed is stable keeping the value of about 400 km/s. The interplanetary magnetic field magnitude is about 5nT. Geomagnetic conditions were quiet during last 24 hours. The arrival of the halo CME, associated with the filament eruption on January 14, is expected at the Earth late on January 18 or in the morning of January 19. We expect quiet geomagnetic conditions in the coming hours.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 039, basierend auf 18 Stationen.
