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.
