Highlights of Solar and Geomagnetic
Activity 18 - 24 April 2016
Solar activity was high on 18 Apr due to an
M6/1f flare observed at
18/0029 UTC from old Region 2529 (N09, L=342,
class/area Eki/850 on
11 Apr). Type II (1869 km/s) and Type IV radio sweeps
were observed
in conjunction with this event, as well as a 120 sfu
Tenflare.
Activity dropped to low levels on 19 Apr with a C1/Sf observed
at
19/2302 UTC. Very low levels were observed for the remainder of
the
period after the region departed the disk.
No proton events were
observed at geosynchronous orbit.
The greater than 2 MeV electron flux at
geosynchronous orbit was at
normal to moderate levels throughout the period.
Geomagnetic field activity was mostly quiet on 18-21 Apr. Quiet
to
unsettled conditions were observed on 22-24 Apr. Isolated
active
periods were observed on 22 and 24 Apr along with an isolated
minor
storm period on 23 Apr due to CH HSS effects.
FORECAST OF SOLAR
AND GEOMAGNETIC ACTIVITY 25 APRIL - 21 MAY 2016
Solar activity is
expected to be very low to low for the majority of
the period with a chance
for M-class flares from 03-16 May due to
the return of old Region 2529.
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 the exception of
01-03 May and 10-13 May
following recurrent CH HSS events.
Geomagnetic field activity is
expected to be quiet to unsettled on
25-26 Apr as CH HSS effects subside
followed by quiet conditions on
27-28 Apr. Quiet to unsettled conditions are
expected on 29 Apr to
01 May with active periods likely due to effects from a
recurrent,
negative polarity CH HSS. An isolated minor storm period is
possible
on 30 Apr. Mostly quiet conditions are expected on 02-08 May
with
unsettled to active periods possible on 04 May due to a SSBC.
Quiet
to active levels are expected on 09-11 May with minor storm
periods
likely due to negative polarity CH HSS effects. Mostly
quiet
conditions are expected from 12-18 May. Isolated unsettled to
active
periods are possible on 14 May due to another SSBC. Quiet
to
unsettled conditions are expected from 19-21 May with isolated
active
periods possible due to effects from a recurrent, positive
polarity CH
HSS.
