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 Nov 19-Nov 21 2025 is 4.00 (below NOAA
Scale levels).

21-00UT       1.67         1.67         4.00

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 Nov 19-Nov 21 2025

              Nov 19  Nov 20  Nov 21
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 Nov 19-Nov 21 2025

              Nov 19        Nov 20        Nov 21
R1-R2           15%           15%           15%
R3 or greater    1%            1%            1%

Rationale: A slight chance for R1-2 (Minor-Moderate) radio blackouts due
to isolated M-class flare activity will persit through 21 Nov due to the
flare potential presented by AR 4284.
