Highlights of Solar and Geomagnetic Activity
20 - 26 May 2024
Solar activity was at low to moderate levels during the period. Low
levels were observed on 20, 25 and 26 May. Moderate (R1-Minor)
levels were observed on 21-24 May. Region 3679 (S09, L=200,
class/area Ekc/500 on 22 May) produced 10 M-class flares, the
largest was an M4.2/1n event at 23/0216 UTC. Region 3689 (S08,
L=098, class/area Dso/050 on 22 May) produced a single M-class flare
on 23 May. No significant radio events were observed. No significant
Earth-directed CMEs were observed.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at
low to normal levels.
Geomagnetic field activity ranged from mostly quiet to unsettled
levels with a single active period observed late on 23 May.
Unsettled to active periods were observed on 23-24 May due to
negative CH HSS influence. Unsettled periods were observed late on
25 May through 26 May due to weak positive CH HSS influence. Total
field readings approached 10 nT on 24-25 May with southward Bz
readings to negative 10 nT late on 23 May. Solar wind readings were
at a predominately steady 400 km/s throughout the period.
Forecast of Solar and Geomagnetic Activity
27 May - 22 June 2024
Solar activity is expected to be at a chance for moderate (R1-R2 /
Minor-Moderate) levels due to the return of previous active region
3664 (S17, L=347).
There will be a slight chance of S1 (Minor) solar radiation storms
from 28 May through 09 Jun upon the return of old region 3664.
The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at low to moderate levels.
Geomagnetic field activity is expected to be at unsettled to active
levels on 27-28 May and 08-12 Jun due to the influence of positive
polarity CH HSSs. Mostly quiet levels are expected on 29-31 May,
01-07 Jun and 13-22 Jun.
