Extended Three Day Forecast:
A. NOAA Geomagnetic Activity Observation and Forecast
The greatest observed 3 hr Kp over the past 24 hours was 6 (NOAA Scale
G2).
The greatest expected 3 hr Kp for Jan 11-Jan 13 2026 is 4.67 (NOAA Scale
G1).

21-00UT 2.67 3.33 3.33
Rationale: G1 (Minor) geomagnetic storms are likely on 11 Jan due to
ongoing influence from a CME that left the Sun on 08 Jan.
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 Jan 11-Jan 13 2026
Jan 11 Jan 12 Jan 13
S1 or greater 1% 1% 1%
Rationale: No S1 (Minor) or greater solar radiation storms are expected.
No significant active region activity favorable for radiation storm
production is forecast.
C. NOAA Radio Blackout Activity and Forecast
No radio blackouts were observed over the past 24 hours.

Jan 11 Jan 12 Jan 13
R1-R2 15% 15% 15%
R3 or greater 1% 1% 1%
Rationale: There exists a slight chance for R1-R2 (Minor-Moderate) radio
blackouts over 11-13 Jan.
Extended Space Weather Discussion:
Solar Activity
.24 hr Summary...
Solar activity remained at low levels. An eruption along a filament
channel was observed near Region 4339 (S13W15, Axx/alpha) beginning
after 10/1930 UTC. Subsequent SOHO/LASCO C2 coronagraph imagery
contained a southward oriented CME signature after 10/2036 UTC. Analysis
and modeling of the event suggested the ejecta would pass below Earths
orbit. No other potentially Earth-directed CMEs were identified in
available coronagraph imagery.
Some minor development was observed in Region 4337 (N28W77, Cro/beta) as
it neared the NW limb. The remaining three regions on the visible disk
were all exhibiting gradual decay.
.Forecast...
Solar activity is expected to be low with a slight chance for M-class
flares (R1/R2-Minor/Moderate) through 13 Jan.
Energetic Particle
.24 hr Summary...
The greater than 2 MeV electron flux reached high levels at 10/1635 UTC,
with an observed peak of 2,507 pfu. The greater than 10 MeV proton flux
was at background levels.
.Forecast...
The greater than 2 MeV electron flux is expected to be at normal to
moderate levels, and the greater than 10 MeV proton flux is expected to
remain at background levels through 13 Jan.
Solar Wind
.24 hr Summary...
Solar wind parameters suggested the arrival of a CME at approximately
10/1939 UTC, when an interplanetary shock was observed at the ACE
spacecraft. Total field increased from 5 nT to a peak of 19 nT. The Bz
component saw a maximum southward deflection to -19 nT. Solar wind
speeds increased from ~450 km/s to a peak of 629 km/s. Tapering CME
effects in the solar wind remained as of this writing.
.Forecast...
Elevated solar wind parameters are expected to continue through 11 Jan
as enhancements from the 08 Jan CME wane. Weaker, yet still elevated
solar wind parameters are likely to continue through 13 Jan as negative
polarity CH HSS influences return after the CME effects wane.
Geospace
.24 hr Summary...
The geomagnetic field reached G2 (Moderate) geomagnetic storm levels. An
approximately 47 nT geomagnetic sudden impulse was observed at 10/2013
UTC at the Heartland (HAD) magnetometer, signaling the onset of a CME
that left the Sun on 08 Jan.
.Forecast...
Geomagnetic field activity is likely to reach G1 (Minor) levels over 11
Jan under waning CME effects. Unsettled to active levels are likely on
12-13 Jan as waning CME effects transition to influence from a negative
polarity coronal hole.
