Highlights of Solar and Geomagnetic Activity 21 - 27 May 2018
Solar activity reached low levels during the period due to an
isolated C-class event, a C2 flare from Region 2712 (N13, L=172,
class/area Csp/80 on 24 May). No Earth-directed CMEs were observed.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit reached
moderate levels on 21-27 May.
Geomagnetic field activity was quiet to unsettled on 23 May due to
influence from a positive polarity, coronal hole high-speed stream
(CH HSS). Quiet conditions were observed throughout the remainder of
the period.
FORECAST OF SOLAR AND GEOMAGNETIC ACTIVITY 28 MAY - 23 JUNE 2018
Solar activity is expected to be very low throughout the period,
with a slight chance for isolated C-class events on 28 May - 04 Jun
and 10-23 Jun, due to flare potential from Regions 2711 (N06, L=288,
class/area Cai/60 on 24 May) and 2712.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is
expected to reach very high levels on 05-07 Jun with high levels
expected on 02-04 Jun and 08-13 Jun. Moderate flux levels are
expected for the remainder of the period.
Geomagnetic field activity is expected to reach G1 (Minor)
geomagnetic storm levels on 02 Jun with active levels on 01, and
03-04 Jun due to the influence of a recurrent, negative polarity CH
HSS. Unsettled levels are expected on 28-29 May and 05-06, 13, 19
Jun. Quiet conditions are expected during the remainder of the
outlook period.
