Highlights of Solar and Geomagnetic Activity
09 - 15 January 2017
Solar activity was mostly at very low levels with low levels
observed on 12 January due to an isolated C3 flare observed at
12/1618 UTC from Region 2625 (N03, L=254, class/area Cso/050 on 14
January). An associated coronal mass ejection (CME) was observed off
the east limb in coronagraph imagery beginning at 12/1624 UTC, but
was determined not to have a geoeffective component. No
Earth-directed CMEs were observed.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels throughout the period. The largest flux of the period
was 42,125 pfu observed at 09/1805 UTC.
Geomagnetic field activity ranged from quiet to active levels over
the period. Solar wind speed began the period near 700 km/s with
total field near 5 nT under the influence of a negative polarity
coronal hole high speed stream (CH HSS). By 10 January, solar wind
speed was in decline, reaching nominal levels late on 12 January.
Total field was variable between 1-7 nT for the rest of the period.
The geomagnetic field responded with quiet to active levels on 09
January, quiet to unsettled levels on 10-12 January and quiet levels
on 13-15 January.
