Highlights of Solar and Geomagnetic
Activity 10 - 16 April 2017
Solar activity was at very low levels
throughout the summary period.
Region 2650 (N11, L=193, class/area=Cao/40 on
11 Apr 2017) produced
numerous B-class flares throughout the period and was
the only
active region with sunspots this period. 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
moderate levels on 16 Apr and high levels on 10-15 Apr with a
peak
flux of 3,860 pfu observed at 1715 UTC on 10 Apr.
Geomagnetic
field activity was at quiet levels on 10, 13, and 16
Apr. Quiet to unsettled
levels were observed on 12 and 15 Apr, and
quiet to active levels were
observed on 11 and 14 Apr due to waning
CH HSS influence and a solar sector
boundary change.
FORECAST OF SOLAR AND GEOMAGNETIC ACTIVITY 17 APRIL -
13 MAY 2017
Solar activity is expected to be very low with a chance for
C-class
flare activity 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 very high levels
on 29-30 Apr and high levels on
18-28 Apr and 01, 06-12 May. Moderate flux
levels are expected
throughout the remainder of the period.
Geomagnetic field activity is expected to reach G2
(Moderate)
geomagnetic storm levels on 23 Apr and G1 (Minor) storm levels
on
17, 24-27 Apr, and 01 May due to the influence of recurrent CH
HSSs.
Active conditions are expected on 19, 28 Apr and 05-06 May
with
generally quiet or quiet to unsettled levels likely throughout
the
remainder of the period.
