Only 6 low-level C-class flares were recorded, with the strongest event a C2.1 flare peaking at 04:52UT. All these flares had NOAA 2253 as their source, the only group that has been actively flaring during the last 24 hours. The negative polarity spot from yesterday's delta structure in NOAA 2253 has moved out of the region's positive polarity leading portion. No CME was associated to yesterday's isolated M-class flare. Some magnetic polarity mixing is present in the trailing portion of NOAA 2255. C-class flaring is expected, with a chance on an isolated M-class flare from NOAA 2253. The geomagnetic field was quiet to unsettled. Solar wind speed decreased from about 500 km/s around 09:30UT (03 January) to its current values just below 400 km/s. Bz was mostly positive till 20:00UT with values up to +8 nT, and steadily becoming negative after 02:00UT with values near -8 nT at the end of the period. In between, Bz was stable near slightly positive values. The influence of the high speed stream from the extension of the southern polar coronal hole is still expected for later today or tomorrow (05 January). The geomagnetic field is expected to be unsettled to active with a chance on a minor geomagnetic storm episode.
