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.
