Bulletin

The strongest flare in last 24 hours was a C6.3 flare peaking at 08:19 UT, on February 5. The flare originated from the NOAA AR 1669, situated at the moment close to the East solar limb. We expect more C-class flares, in particular from this active region. The interplanetary magnetic field is about 3 nT. The solar wind speed is stable having value of about 350 km/s. The small low-latitude coronal hole in the southern hemisphere has reached the central meridian. We expect arrival of the associated fast flow early on February 9. The fast flow associated with the low-latitude coronal hole in the northern hemisphere should arrive late today or early tomorrow. The geomagnetic conditions in the next 48 hours should be quiet to possibly active.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 028, basierend auf 12 Stationen.
