Highlights of Solar and Geomagnetic Activity
30 May - 05 June 2022
Solar activity ranged from very low to low levels throughout the
highlight period. On 30 May, Region 3019 (N11, L=042, class/area
Cro/030 on 21 May) produced a C1.5 flare at 30/0027 UTC. Weak
C-class activity was also observed from Region 3029 (S18, L=199,
class/area Axx/010 on 04 Jun) on 02 Jun and 04 Jun. A 6 degree long
filament erupted at 31/2351 UTC, centered near S11W08. A CME was
detected in STEREO imagery, first visible at 01/0224 UTC, with a
possible Earth-directed component. Another filament eruption was
observed at 02/0500 UTC. This 20 degree long filament was centered
near S35W35 with a subsequent CME detected in LASCO imagery at
02/0612 UTC and with a possible Earth-directed conponent.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at
high levels through the period. A maximum of 9,720 pfu was observed
at 03/1515 UTC.
Geomagnetic field activity was at quiet to unsettled levels.
Isolated unsettled levels were observed on 30-31 May due to
recurrent, negative polarity CH HSS influence. Quiet levels were
observed on 01-05 Jun.
Forecast of Solar and Geomagnetic Activity
06 June - 02 July 2022
Solar activity is expected to be at very low to low levels through
the outlook period. A chance for moderate levels exists on 08-24 Jun
due to the return of old Regions 3014 (N22, L=104) and 3017 (N12,
L=089), both M-class flare producers on their last transit.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is
expected to reach high levels on 26-30 Jun and 01-02 Jul due to CH
HSS effects. Normal to moderate levels are anticipated on 06-25 Jun.
Geomagnetic field activity is expected to be at unsettled to active
levels on 13-17 Jun and 23-26 Jun due to recurrent CH HSS
influences. Mostly quiet conditions are expected to prevail
throughout the remainder of the outlook period.
