Extended Three Day Forecast:
A. NOAA Geomagnetic Activity Observation and Forecast
The greatest observed 3 hr Kp over the past 24 hours was 4 (below NOAA
Scale levels).
The greatest expected 3 hr Kp for Jan 10-Jan 12 2026 is 5.33 (NOAA Scale
G1).

21-00UT 4.67 (G1) 3.67 3.33
Rationale: G1 (Minor) geomagnetic storms are likely over 10-11 Jan due
to potential influence of CMEs that departed the Sun on 08 Jan combined
with an anticipated CH HSS.
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 10-Jan 12 2026
Jan 10 Jan 11 Jan 12
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.
Radio Blackout Forecast for Jan 10-Jan 12 2026
Jan 10 Jan 11 Jan 12
R1-R2 15% 15% 20%
R3 or greater 1% 1% 1%
Rationale: There exists a slight chance for R1-R2 (Minor-Moderate) radio
blackouts over 10-12 Jan due primarily to the flare potential of Region
4336.
Extended Space Weather Discussion:
Solar Activity
.24 hr Summary...
Solar activity was at low levels with the largest flare of the period
being a C1.2 flare at 09/2230 UTC from beyond the the SE limb. Region
4334 (S16W26, Hax/beta) exhibited decay as it decreased in total area,
decay in its leader spot, and became unipolar. Region 4336 (S10E07,
Eko/beta-gamma-delta) underwent decay as well, but maintained a weak
delta signature in its large, leading spot group and produced a C1.1/SF
flare at 10/0814 UTC in this period. Region 4339 (S16W01, Bxo/beta)
emerged in the last period and was unremarkable. Region 4337 (N25W67,
Bxo/beta) is in a state of decay and simplification.
No Earth-directed CMEs were observed this period.
.Forecast...
Solar activity is expected to be low with a slight chance for M-class
flares (R1/R2-Minor/Moderate) through 12 Jan. Probabilities increase
slightly after 11 Jan, due to possible returning regions.
Energetic Particle
.24 hr Summary...
The greater than 2 MeV electron flux remained at moderate levels. The
greater than 10 MeV proton flux was at background levels.
.Forecast...
The greater than 2 MeV electron flux is expected to remain at moderate
levels with a chance for high levels on 11 Jan before an overall
decrease back to normal to moderate levels is likely on 13 Jan due to
glancing CME effects. The greater than 10 MeV proton flux is expected to
remain at background levels through 12 Jan.
Solar Wind
.24 hr Summary...
Solar wind parameters suggested negative polarity CH HSS influences.
Total field reached a peak of 12 nT. The Bz component of the IMF was
mostly northward or near neutral, though it experienced several periods
of southward deflections reaching -8 nT. Solar wind speeds showed minor
fluctuations, generally ranging between 430 km/s and 550 km/s. The Phi
angle was mostly in the negative (towards) sector. Density remained
unremarkable, generally hovering between 3 and 8 particles/cm^3.
.Forecast...
Negative polarity CH HSS influences are expected to continue through 12
Jan. Additional enhancements are likely by late 10 Jan into early 11 Jan
due to glancing CME effects from a filament eruption that occurred on 08
Jan.
Geospace
.24 hr Summary...
The geomagnetic field was quiet to active levels.
.Forecast...
Periods of G1 (Minor) geomagnetic storming are likely 10-11 Jan due to
aforementioned CH HSS effects with combined with anticipated CME effects
beginning later on 10 Jan. Chances for G2 (Moderate) storming periods
are present as well if the CMEs have a more Earth-directed component and
are not as southward as the model projects. Geomagnetic field activity
is expected to decrease to unsettled to active levels on 12 Jan as any
CME effects wane.
