Highlights of Solar and Geomagnetic Activity
25 - 31 May 2020

Solar activity reached moderate levels on 29 May due to an M1.1
flare at 0724 UTC from an unnumbered region beyond the northeast
limb. This region also produced a C9.3 flare at 29/1046 UTC. Both
flares were believed to cause CMEs off the eastern limb. However, no
Earth-directed CMEs were observed in LASCO coronagraph imagery. Very
low activity was observed for the remainder of the summary period. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at
normal background levels. 

Geomagnetic field activity was quiet to unsettled for the period.
There was possible CME influence on 30 May. The IMF was enhanced to
a peak of 14 nT near 30/0500 UTC, while the Bz component reached a
maximum southward deflection of -13 nT at 30/0520 UTC. However, the
geomagnetic field only managed unsettled levels. 

Forecast of Solar and Geomagnetic Activity
01 June - 27 June 2020

Solar activity is expected to be very low for the period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at normal to moderate levels for the forecast period. 

Geomagnetic field activity is expected to be at mostly quiet levels
for the period.
