Bulletin

There are currently eight numbered sunspot groups on the solar disc, and the most active one is the NOAA AR 1959. The strongest of 8 C-class flares observed in last 24 hours was C6.0 flare (peaking at 12:04 UT of January 18) which also originated from the NOAA AR 1959 currently situated close to the East solar limb. We expect more C-class flares and possibly also an isolated M-class flare. The solar wind speed is about 290 km/s. The interplanetary magnetic field is still stable with the magnitude between 2 and 3 nT. The low-latitude coronal hole in the northern hemisphere has reached the central meridian early on January 18. We expect arrival of the fast solar wind on January 20-21. The CME-driven shock wave, associated with a partial halo CME (limb event) on January 16, could be also expected on January 20-21. We expect quiet to possibly unsettled geomagnetic conditions in the next 48 hours.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 073, sur la base de 09 stations.
