25 Jan 26 Jan 27 Jan Activity Very low to low Very low to low Very low to low Fadeouts None expected None expected None expected 10.7cm/SSN 95/41 95/41 95/41 COMMENT: Solar activity was low on UT day 24 January with two C1 flares. There are two numbered regions on the visible disc. Spot region 2934 (S23E10) is stable and quiet. A yet to be numbered region is located near N13E79, there is a developing spot group near N32E06 and there has been intermittent spot development and decay in the northern hemisphere. Solar activity is expected to be very low to low on 25-27 January. There were no Earth directed coronal mass ejections seen in available images. Ambient solar wind conditions were observed on 24 January with a peak speed of 338 km/s. The peak total IMF was 7 nT until 1710 UT when a small step occurred, with the total IMF peaking at 11 nT after that. The north-south IMF (Bz) range was +/-6 nT. Coronal hole effects are expected to produce mildly enhanced solar wind conditions 25-26 January. There is a slight chance of a mild CME impact in the second half of 25 January. The solar wind is expected to begin to settle on 27 January.
