Bülletään

Solar activity was very low. NOAA 2629, a new sunspot region near the east limb, developed quickly into a mature group and produced a series of B-class flares. The strongest event was a B5 flare peaking at 17:55UT. No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery. The greater than 10MeV proton flux was at nominal levels.

Mostly quiet flaring conditions are expected, with a chance on a C-class event in particular from NOAA 2629.

Solar wind speed varied between 310 and 350 km/s (ACE). Bz intensified somewhat and was fluctuating between -6 nT and +6 nT. The interplanetary magnetic field was mostly directed away from the Sun. A small positive equatorial coronal hole (CH) transited the central meridian.

The geomagnetic field was at quiet to unsettled levels and is expected to remain so. The CH's particle stream is expected to arrive at Earth around 27 January and may result in active to minor storming episodes.
