Highlights of Solar and Geomagnetic Activity
23 - 29 May 2022
Solar activity ranged from very low to moderate levels throughout
the week. Moderate solar activity was observed on 25 May when an
M1/1n flare was observed at 25/1824 UTC from Region 3016 (S19,
L=074, class/area=Dao/180 on 18 May), which was the largest event of
the period. Solar activity was low on 23-24, and 26-28 May, and very
low levels were observed on 29 May. Regions 3014 (N24, L=105, class/area=Dkc/1190 on 20 May) and 3017 (N13, L=085,
class/area=Dai/130 on 23 May) were the most active and complex
regions on the disk this period. No Earth-directed CMEs were
detected this period.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was
normal to moderate throughout the week.
Geomagnetic field activity reached minor storm levels on 27-28 May
due to negative polarity CH HSS influence. Geomagnetic field
conditions were quiet and quiet to unsettled throughout the
remainder of the period.
Forecast of Solar and Geomagnetic Activity
30 May - 25 June 2022
Solar activity is expected to be at mostly low levels throughout the
period. M-class flare activity is possible on 07-22 Jun.
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 30 May-04 Jun, and be predominately
normal to moderate on 05-25 Jun.
Geomagnetic field activity is expected to reach minor storm levels
on 24 Jun, and active levels on 12-13, 16-17, and 23 Jun, due to
recurrent CH HSS influences. Quiet and quiet to unsettled conditions
are expected to prevail throughout the remainder of the period.
