Solar activity was very low. Region 715 (N06w59) has decayed to a small single polarity sunspot. New Region 718 (S09E78) was numbered today and was responsible for occasional B-class flares. Another active region is rotating into view near S12.

Solar activity is expected to be very low to low. Isolated C-class activity is possible from active regions near the southeast limb.

The geomagnetic field ranged from quiet to major storm levels. Transient flow, likely the CME activity from 04 and 05 January, impacted the geomagnetic field first at around 07/0900Z. The existing elevated solar wind speed increased from 500 km/s to just over 600 km/s. The major storming followed a period of sustained southward Bz to near -10 nT between 07/1300 - 1500Z. A second disturbance passed the ACE spacecraft at 07/2010Z. Only a weak enhancement was observed on the plasma measurements; however, the IMF Bz turned sharply southward to near -15 nT. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels again this period. The energetic electrons, which have been sustained at high levels since 03 January, dropped below the high threshold at approximately 07/1900Z.

The geomagnetic field is expected to range from quiet to major storm levels. Transient flow from the CME activity on 04 and 05 January will continue the current disturbance through 08 January. Periods of minor to major storming are expected on the 8th. Quiet to active levels are expected on 09 January, before gradually returning to predominantly quiet conditions on 10 January.
