Highlights of Solar and Geomagnetic
Activity 27 July - 02 August 2015
Solar activity was dominated by B-class
flare activity (very low
levels) throughout the majority of the summary
period, however,
Region 2390 (S17, L=199, class/area=Dai/170 on 27 Jul)
produced a
single C1 flare (low levels) at 01/2005 UTC, which was the
largest
event of the period. No Earth-directed coronal mass ejections
(CMEs)
were observed during the summary period.
No proton events were
observed at geosynchronous orbit.
The greater than 2 MeV electron flux at
geosynchronous orbit was at
normal levels on 31 Aug with moderate levels
observed throughout the
remainder of the summary period.
Geomagnetic
field activity reached active levels on 27, 30-31 Jul
and 02 Aug in response
to an enhanced solar wind environment caused
by the influence of multiple
weak coronal hole high speed streams
(CH HSSs). Geomagnetic field activity
remained at quiet to unsettled
levels throughout the remainder of the summary
period.
FORECAST OF SOLAR AND GEOMAGNETIC ACTIVITY 03 AUGUST - 29 AUGUST
2015
Solar activity is expected to be at very low (B-class
flare
activity) to low levels (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 be at moderate levels on 07-08, 17-21, 23, and 26-29 Aug
in
response to enhanced geomagnetic field activity cause by the
influence of
multiple recurrent coronal hole high speed streams (CH
HSSs). High electron
flux levels are expected for the remainder of
the outlook period.
Geomagnetic field activity is expected to reach G1
(Minor)
geomagnetic storm levels on 28 Aug with active levels expected
on
06-07, 17, 20, 26-27, and 29 Aug, all due to the influence of
multiple
recurrent CH HSSs. The geomagnetic field is expected to be
at quiet to
unsettled levels throughout the remainder of the
outlook
period.
