Highlights of Solar and Geomagnetic Activity 02 - 08 January 2017
Solar activity was at very low levels with only a few low level   B-class flares observed. The solar disk was mostly spotless throughout the period. No Earth-directed coronal mass ejections were
observed.  No proton events were observed at geosynchronous orbit. The greater than 2 MeV electron flux at geosynchronous orbit was normal to moderate levels with high levels observed on the 05-08 of January. The largest flux value of the period was 25,537 pfu observed at 08/1935 UTC. The geomagnetic field activity was at quiet to unsettled levels on 02 January under a nominal solar wind  environment. By 03 January, a solar sector boundary crossing was observed at approximately 03/0956 UTC. By  transitioning into a negative sector followed by increase in solar wind speed and total field indicating the onset of a negative polarity coronal hole high speed stream (CH HSS). Total fiel increased to a maximum of 15 nT on 04/0444 UTC. Solar wind increased from approximately 372 km/s to 695 km/s by 05/1423 UTC. Solar wind speeds continued near 670 km/s through the rest of the period. The geomagnetic field responded with quiet to active levels from 03-08 January.

Forecast of Solar and Geomagnetic Activity 09 January - 04 February 2017
Solar activity is expected to be at very low levels with low levels possible from 12-26 January due to the return of old Region 2621 (N10, L=237). No proton events are expected at geosynchronous orbit. The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal to moderate levels with high levels likely on 9-10, 12-16, 18-27 January and on 01-04 February due to CH HSS influence. Geomagnetic field activity is expected to be at unsettled to active levels on 09, 11-14, 17-23, and 27 January through 04 February with G1 (Minor) storm levels likely on 17-19, 21-22 January, and again on 03 February due to recurrent CH HSS effects.
