Highlights of Solar and Geomagnetic
Activity 18 - 24 December 2017
Solar activity was at very low levels
throughout the period. Region
2692 (N18, L=087, class/area=Eai/160 on 24 Dec)
was the only active
region with sunspots this period and produced multiple
low and
mid-level B-class flares throughout the week. 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 on 18-23 Dec with moderate levels observed on 24 Dec.
Geomagnetic field activity reached active levels early on 18 Dec
in
response to the influence of a recurrent, positive polarity CH
HSS.
Quiet to unsettled conditions were observed on 19 and 23-24 Dec
and
generally quiet conditions were observed throughout the remainder
of
the week under a nominal solar wind regime.
FORECAST OF SOLAR AND
GEOMAGNETIC ACTIVITY 25 DEC 2017 - 20 JAN 2018
Solar activity is expected
to persist at very low levels throughout
the 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 on 26-30 Dec,
02-06 and 14-19 Jan.
Normal and normal to moderate greater than 2 MeV
electron flux
values are expected throughout the remainder of the forecast
period.
Geomagnetic field activity is likely to reach G1 (Minor)
geomagnetic
storm levels on 01 and 13 Jan with active levels expected on 25
Dec
and 02, 08, 14 and 20 Jan under the influences of multiple,
recurrent
CH HSSs. Quiet and quiet to unsettled conditions are
expected throughout the
remainder of the forecast period.
