Highlights of Solar and Geomagnetic
Activity 26 Dec 2016 - 01 Jan 2017
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 was at
high levels from 26-31 Dec, dropping to normal to
moderate levels
late on 31 Dec - 01 Jan due to increased geomagnetic activity
from
the onset of a positive polarity CH HSS.
Geomagnetic field
activity ranged from quiet to G1 (Minor) storm
levels through the period. G1
conditions were observed early on 26
Dec as influence from a positive
polarity CH HSS persisted from the
previous reporting period. The CH HSS
began to wane early on 27 Dec,
causing a geomagnetic activity decrease to
quiet to active levels.
As solar wind speeds continue their slow decline,
quiet to unsettled
conditions on 28 Dec gave way to quiet conditions on 29-30
Dec.
Quiet to unsettled activity was once again observed beginning on
31
Dec as the onset of another positive polarity CH HSS was observed.
Wind
speeds increased from around 300 km/s to between 450-550 km/s
as well as
total magnetic field strength from around 5 nT to a peak
of nearly 20 nT at
31/1636 UTC. Active conditions were observed
early on 01 Jan as the CIR
transitioned into the high-speed stream
proper. As total magnetic field
strength gradually trended towards 5
nT, geomagnetic activity decreased to
quiet to unsettled levels.
FORECAST OF SOLAR AND GEOMAGNETIC ACTIVITY 02
- 28 JANUARY 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 be high on 02-03 Jan, 05-13 Jan, and
18-27 Jan; moderate
electron flux is expected on 04 Jan, 14-17 Jan and 28
Jan. All
increases in electron flux are anticipated in response to
multiple,
recurrent CH HSSs
Geomagnetic field activity is expected to
be at unsettled levels on
02 Jan, 08 Jan, 14 Jan and 23 Jan; active levels
are expected on
03-04 Jan, 06-07 Jan, 20-22 Jan and 27-28 Jan; G1 (Minor)
storm
levels are likely on 05 Jan and 17-19 Jan. All elevated
geomagnetic
activity is anticipated in response to multiple, recurrent CH
HSSs.
The remainder of the outlook period is expected to observe
quiet
conditions under an ambient solar wind environment.
