Highlights of Solar and Geomagnetic
Activity 16 - 22 January 2017
Solar activity was at low levels due to a
C9/1f flare observed at
21/0726 UTC from Region 2628 (N12, L=173, class/area
Dao/210 on 22
January). Region 2628 was responsible for additional C-class
flaring
on 21 January. The rest of the period was at very low levels.
No
Earth-directed coronal mass ejections were observed.
No proton
events were observed at geosynchronous orbit.
The greater than 2 MeV
electron flux at geosynchronous orbit was at
normal to moderate levels with
high levels observed on 16-17, and
20-22 January. The largest flux value of
the period was 3,090 pfu
observed at 16/1935 UTC.
Geomagnetic field
activity ranged from quiet to active levels over
the period. Solar wind
parameters were indicative of background
conditions to start the period.
Early on 18 January, wind speed
began to increase as a positive polarity
coronal hole high speed
stream (CH HSS) became geoeffective. Wind speed
reached a maximum
value of 651 km/s at 19/0320 UTC and total field peaked at
17 nT at
18/0605 UTC before gradually decreasing throughout the remainder
of
the period. The geomagnetic field was at quiet levels on 16-17
January,
quiet to active levels on 18-19 & 21 January, and quiet
to unsettled
levels on 20 & 22 January.
FORECAST OF SOLAR AND GEOMAGNETIC
ACTIVITY 23 JANUARY-18 FEBRUARY 2017
Solar activity is likely to be low
with a slight chance for M-class
flares on 23-31 January and 14-18 February
due to the flare
potential in Region 2628. Very low levels are expected on
01-13
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
23-27 January, 01-13 February, and again on 16-18 February due to
CH HSS
influence.
Geomagnetic field activity is expected to be at unsettled to
active
levels on 23, 27-31 January, 01-07 February and 14-18 February
with
G1 (Minor) geomagnetic storm levels likely on 03 February due
to
recurrent CH HSS effects.
