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. is the U.S. government's official web portal to all federal, state and local government web resources and services.
