Solar activity was very low. B-class flare production by NOAA 2629 pretty much stalled. NOAA 2627, now spotless, produced the strongest event of the period: an isolated B5 flare peaking at 10:45UT. NOAA 2628 showed some filament activity in its middle portion around midnight. 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 small chance on a C-class event.

Around 26/13:45UT January, solar wind speed gradually increased from an initial 375 km/s up to values near 670 km/s around 06UT on 27 January. This is the High Speed Stream (HSS) from the positive equatorial coronal hole (CH), arriving somewhat earlier than expected. It was preceded by a co- rotating interaction region (CIR) that drove a weak shock on 26/07:12UT January. Bz oscillated wildly between -12 nT and +13 nT, preventing the development of a geomagnetic storm. Since 06UT, Bz varied between +5 nT and -5 nT, and wind speed at 560 km/s. The interplanetary magnetic field was mostly directed away from the Sun.

The geomagnetic field was at quiet to active levels. The earth environment will probably remain under the influence of the HSS until at least 28 January. Quiet to active geomagnetic conditions are expected, with a minor storming episode not excluded.
