Highlights of Solar and Geomagnetic
Activity 19 - 25 December 2016
Solar activity was at background levels
through the period.
No proton events were observed at geosynchronous
orbit.
The greater than 2 MeV electron flux at geosynchronous orbit
reached
high levels throughout the reporting period with a peak flux
of
29,524 pfu on 24/1830 UTC.
Geomagnetic field activity was quiet
levels on 19 Dec and mostly
quiet levels with an isolated period of unsettled
conditions on 20
Dec. Activity increased to active with an isolated period of
G2
(Moderate) storm levels late on 21 Dec due to the onset of a
positive
polarity CH HSS increasing wind speeds from around 350 km/s
to over 650 km/s.
An isolated period of G1 (Minor) was observed
early on 22 Dec before
geomagnetic activity decreased to unsettled
and activity conditions through
23 Dec. 24 Dec underwent a further
decrease with quiet to unsettled
conditions throughout the day
despite wind speeds maintaining between 600-750
km/s. Quiet to
unsettled conditions were isolated by frequent periods of
active
levels on 25 Dec as the influence of a positive polarity CH
HSS
continued to keep solar wind speeds enhanced to around 700 km/s.
FORECAST OF SOLAR AND GEOMAGNETIC ACTIVITY 26 DEC 2016 - 21 JAN
2017
Solar activity is expected to be at very low levels throughout
the
outlook period.
No proton events are expected at geosynchronous
orbit.
The greater than 2 MeV electron flux at geosynchronous orbit
is
expected to reach high levels from 26-29 Dec, 31 Dec-02 Jan, 04-13
Jan,
and 18-21 Jan due to multiple CH HSS influences; normal to
moderate levels
are expected on 30 Dec, 03 Jan, and 14-17 Jan.
Geomagnetic field
activity is expected to be at quiet to G1 (Minor)
levels on 26 Dec due to CH
HSS influences. G1 (Minor) conditions are
also likely on 04-05 Jan and 17-19
Jan. Active conditions are likely
on 30 Dec, 06-07 Jan, and 20-21 Jan.
Unsettled conditions are likely
on 31 Dec, 02-03 Jan, 08 Jan, and 14 Jan. All
anticipated
enhancements in field activity are due to recurrent CH HSSs.
Mostly
quiet conditions are expected for the remainder of the
outlook
period.
