Extended Three Day Forecast:
A. NOAA Geomagnetic Activity Observation and Forecast
The greatest observed 3 hr Kp over the past 24 hours was 2 (below NOAA
Scale levels).
The greatest expected 3 hr Kp for Feb 01-Feb 03 2026 is 1.67 (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 01-Feb 03 2026
Feb 01 Feb 02 Feb 03
S1 or greater 5% 5% 10%
Rationale: S1 (Minor) or greater probabilities begin to increase on 03
Feb as Region 4366 rotates into a more favorable location for
connection.
C. NOAA Radio Blackout Activity and Forecast
Radio blackouts reaching the R2 levels were observed over the past 24
hours. The largest was at Feb 01 2026 1212 UTC.
Radio Blackout Forecast for Feb 01-Feb 03 2026
Feb 01 Feb 02 Feb 03
R1-R2 55% 55% 55%
R3 or greater 10% 10% 10%
Rationale: R1-R2 (Minor-Moderate) radio blackouts due to M-class flares,
with a slight chance for an isolated X-class event (R3 or greater), will
persist through 03 Feb given the evolution and history of Region 4366.
Extended Space Weather Discussion:
Solar Activity
.24 hr Summary...
Solar activity reached high levels with several M-class flares from
Region 4366 (N14E40, Eac/beta-gamma-delta). The largest event was an
M6.6 flare which peaked at 01/1002 UTC. This event was relatively
impulsive, but was quickly followed by another M2.4 flare at 01/1042
UTC. No subsequent CME was observed, but investigation analysis
continues as of the time of this writing and as coronagraph imagery
becomes available. A new relatively large spot with apparent symmetric
penumbra was observed rotating into view on the eastern limb, but
remains unnumbered at this time as we await corroborating observatory
reports.
.Forecast...
Solar activity will likely continue at moderate to high levels due to
M-class flares (R1-R2 Radio Blackouts), with a slight chance for an
isolated X-class flare (R3 Strong or Greater), through 03 Feb given the
evolution and history of Region 4366.
Energetic Particle
.24 hr Summary...
The greater than 2 MeV electron flux reached high levels with a peak
flux of 11,110 pfu observed at 31/1725 UTC. The greater than 10 MeV
proton flux was below the S1 (Minor) threshold.
.Forecast...
The greater than 2 MeV electron flux is expected to continue at moderate
to high levels through 03 Feb. The greater than 10 MeV proton flux is
expected to remain below the S1 (Minor) solar radiation storm 10 pfu
threshold through 03 Feb. However, probabilities for an event begin
increasing slightly on 03 Feb as Region 4366 will begin to rotate into a
more favorable position for connection by that date given any
significant eruptive event.
Solar Wind
.24 hr Summary...
Solar wind parameters reflected a return to an ambient-like state.Total
field ranged 3-6 nT, the Bz component was mostly near neutral with a
late southward deflection reaching -4 nT, and solar wind speeds
gradually fell to below 350 km/s. Phi was predominantly negative with a
brief turn into the positive solar sector between 01/0240 UTC and
01/0429 UTC.
.Forecast...
An ambient-like regime is expected to continue through 03 Feb barring
new, significant eruptive events.
Geospace
.24 hr Summary...
Geomagnetic field activity was at quiet levels.
.Forecast...
Mostly quiet conditions are expected to prevail through 03 Feb while an
ambient solar wind regime persists.
