23 Jun 24 Jun 25 Jun Activity Very low Very low Very low Fadeouts None expected None expected None expected 10.7cm/SSN 80/20 80/20 78/17 COMMENT: Solar activity was Very Low for 22Jun. There is currently three numbered sunspots on the visible disk with region 2714 (N08W80) set to rotate behind the west limb. Region 2715 (N04W07) was quiet and has decreased in overall size during the last 24 hours and region 2713 (N04W62) was the source of minor B-class events. No earthward directed CME's were observed in available LASCO imagery. The solar wind speed continued to decline to ambient levels, beginning the UT day at ~380km/s and is currently ~330km/s at the time of this report. Solar wind speed is expected to remain at low levels for the next 24 hours after which there is an expected increase on 24Jun due to coronal hole effects. The magnitude of the north-south component of the IMF (Bz) has gradually increased, ranging between +/-2nT at 00UT to being mostly southward at -4nT at the time of this report. Solar activity is expected to be Very Low for the next three days with the slight chance of C-class flares.
