Solar activity remained at low levels. NOAA active region 2732 produced one B4.2 flare peaking at 11:35 UT yesterday. No geoeffective coronal mass ejections (CMEs) were observed over the last 24 hours. The greater than 10 MeV proton flux was at nominal values. Solar activity is expected to remain at low levels with some probability for C-class flares. Solar wind speed, gradually increased from about 350 till 520 km/s over the past 24 hours due to the influence of the wind stream associated with the negative polarity equatorial coronal hole. Bz varied between -9.5 and +9.5 nT and the total interplanetary magnetic field reached the value of 11 nT. Geomagnetic conditions reached minor storm level this morning 00-03UT, active conditions during 03-06UT and returned to quiet levels later due to decreased variations of Bz component. In spite of growing solar wind speed (expected to reach maximum value of 600 km/s this midnight, January 5), mostly unsettled to active geomagnetic conditions can be expected today and tomorrow. Isolated episode of minor geomagnetic storm is still possible due to the patchy structure of the coronal hole in the geoeffective position (Bz variations have some chance to increase again).
