A. NOAA Geomagnetic Activity Observation and Forecast
The greatest observed 3 hr Kp over the past 24 hours was 3 (below NOAA
Scale levels).
The greatest expected 3 hr Kp for Feb 02-Feb 04 2026 is 2.67 (below NOAA
Scale levels).

Rationale: No G1 (Minor) or greater geomagnetic storms are expected. No
significant transient or recurrent solar wind features are forecast.
B. NOAA Solar Radiation Activity Observation and Forecast
Solar radiation, as observed by NOAA GOES-18 over the past 24 hours, was
below S-scale storm level thresholds.
Solar Radiation Storm Forecast for Feb 02-Feb 04 2026
Feb 02 Feb 03 Feb 04
S1 or greater 65% 50% 50%
Rationale: S1 (Minor) or greater solar radiation storms are likely on 02
Feb due to the eruptive X8.1 event that occurred late on 01 Feb. Chances
diminish slightly thereafter but remain at a high chance given the
history and potential currently exhibited by AR 4366.
C. NOAA Radio Blackout Activity and Forecast
Radio blackouts reaching the R3 levels were observed over the past 24
hours. The largest was at Feb 01 2026 2357 UTC.
Radio Blackout Forecast for Feb 02-Feb 04 2026
Feb 02 Feb 03 Feb 04
R1-R2 80% 80% 80%
R3 or greater 40% 40% 40%
Rationale: R1-R2 (Minor-Moderate) radio blackouts due to M-class flares
are expected to continue through 04 Feb, with a high chance of
occasional R3 (Strong) or greater events due to X-class flares, given
the history and flare potential currently exhibited by AR 4366.
Extended Space Weather Discussion:
Solar Activity
.24 hr Summary...
Solar activity was at very high levels. Region 4366 (N14E28,
Ekc/beta-gamma-delta) continued to evolve in its growth phase as it
increased in size, gained new spots and maintained a few spots of
opposite polarity inside maturing asymmetric penumbra. AR 4366 produced
nineteen M-class flares and four X-class flares during the reporting
period. The most notable of the X-class events were an X8.1 flare at
01/2357 UTC, an X2.8 flare at 02/0036 UTC and an X1.6 flare at 02/0814
UTC. Additionally new spots were noted near S21E77, but remain
unnumbered at this time due to classification uncertainty caused by limb
foreshortening.
A complex eruption resulting in possibly three CMEs was associated with
the X8.1 and X2.8 event. The first CME front became visible in LASCO C2
coronagraph imagery at approximately 02/0012 UTC followed by another at
02/0048 and the third at perhaps 02/0126 UTC, with the latter being
difficult to discern due to degraded imagery. A STEREO-A COR2 gap was
also occuring during this time, further compounding the uncertaintly of
anlaysis. Initial modeling efforts of this event returned with possible
glancing blows at Earth beginning to arrive by late on 05 May. We await
further adequate coronagraph imagery to analyze the aformentioned later
events.
.Forecast...
Moderate solar activity due to M-class flares is expected for the next
three days with a high chance for occasional X-class flare events due to
continued frequent activity from AR 4366.
Energetic Particle
.24 hr Summary...
The greater than 10 MeV proton flux at geosynchronous orbit remained at
background levels. The greater than 2 MeV electron flux continued to
reach high levels with a peak flux of 10,020 pfu at 01/1450 UTC.
.Forecast...
The greater than 2 MeV electron flux is expected to remain at moderate
to high levels through 04 Feb. The greater than 10 MeV proton flux is
likely to exceed the S1 (Minor) levels on 02 Feb with a chance on 03-04
Feb due to the recent X8.1 flare event from AR 4366 and possible future
eruptions UTC.
Solar Wind
.24 hr Summary...
Available solar wind measurements at L1 were absent transient or
recurrent influences. Solar wind speed declined from ~350 to ~300 km/s.
Total field ranged 4-7 nT and the Bz component was mostly benign, only
undergoing minor southward deflections. Phi was predominantly in a
negative orientaion.
.Forecast...
A quiescent solar wind regime is expected to continue through 04 Feb
barring any significant eruptive events.
Geospace
.24 hr Summary...
The geomagnetic field was quiet with an isolated unsettled period.
.Forecast...
The geomagnetic field is expected to remain quiet through 04 Feb.
