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.
FORECAST OF SOLAR AND GEOMAGNETIC ACTIVITY 16 JANUARY-11
FEBRUARY 2017
Solar activity is expected to be very low with a chance for
C-class
flares on 16-26 January as Regions 2625 and 2626 (N09,
L=244,
class/area Hax/140 on 15 January) rotate across the visible
disk.
Very low levels are expected from 27 January through 11 February.
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 16, 18-27 January and
again on 01-11 February due to CH HSS
influence.
Geomagnetic field
activity is expected to be at unsettled to active
levels on 17-24 and 27
January-07 February with G1 (Minor)
geomagnetic storm levels likely on 18-19
January and 03 February due
to recurrent CH HSS effects
