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 Dec 30-Jan 01 2026 is 5.00 (NOAA Scale
G1).

Rationale: No G1 (Minor) or greater geomagnetic storms are expected
through 31 Dec. G1 (Minor) geomagnetic storms are likely on 01 Jan due
to recurrent solar wind features combined with potential transient
features.

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.

S1 or greater 10% 10% 10%

Rationale: There is a slight chance for a flux above the S1 (Minor) or
greater threshold due to the flaring potential of the active regions on
the visible solar disk.

C. NOAA Radio Blackout Activity and Forecast

Radio blackouts reaching the R1 levels were observed over the past 24
hours. The largest was at Dec 29 2025 0651 UTC.

There is a slight chance for isolated R3 (Strong) events during the
3-day period.

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 05-Jan 07 2026

Jan 05 Jan 06 Jan 07
S1 or greater 10% 10% 10%

Rationale: There remains a slight chance for S1 (Minor) or greater solar radiation storms over 05-07 Jan.

C. NOAA Radio Blackout Activity and Forecast

No radio blackouts were observed over the past 24 hours.

Radio Blackout Forecast for Jan 05-Jan 07 2026

Jan 05 Jan 06 Jan 07
R1-R2 50% 50% 50%
R3 or greater 10% 10% 10%

Rationale: There exists a chance for R1-R2 (Minor-Moderate) radio
blackouts, with a slight chance for R3 (Strong), over 05-07 Jan.

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 Jan 08-Jan 10 2026 is 5.00 (NOAA Scale
G1).

21-00UT 3.00 3.67 2.67

Rationale: G1 (Minor) or greater geomagnetic storms are anticipated on
09 Jan due to a coronal high speed stream interacting with a potential
glancing blow from a CME that left the Sun on 06 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 08-Jan 10 2026

S1 or greater 10% 10% 10%

Rationale: There is a slight chance for a S1 (Minor) or greater solar
radiation storm 08-10 Jan.

C. NOAA Radio Blackout Activity and Forecast

No radio blackouts were observed over the past 24 hours.

Radio Blackout Forecast for Jan 08-Jan 10 2026

Jan 08 Jan 09 Jan 10
R1-R2 45% 45% 45%
R3 or greater 10% 10% 10%

Rationale: There is a chance for R1-R2 (Minor-Moderate) radio blackouts,
with a slight chance for R3 (Strong) or greater events, on 08-10 Jan.
