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 30-Feb 01 2026 is 3.67 (below NOAA
Scale levels).

21-00UT       2.67         2.33         1.33

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 Jan 30-Feb 01 2026

              Jan 30  Jan 31  Feb 01
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 30-Feb 01 2026

              Jan 30        Jan 31        Feb 01
R1-R2           15%           10%           10%
R3 or greater    1%            1%            1%

Rationale: A slight chance for R1-2 (Minor-Moderate) radio blackouts due
to isolated M-class activity will presist through 04 Feb.
