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 24-Nov 26 2020 is 4 (below NOAA
Scale levels).

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-16 over the past 24 hours, was
below S-scale storm level thresholds.

Solar Radiation Storm Forecast for Nov 24-Nov 26 2020

              Nov 24  Nov 25  Nov 26
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 24-Nov 26 2020

              Nov 24        Nov 25        Nov 26
R1-R2           10%           10%           15%
R3 or greater    1%            1%            1%

Rationale: There is a slight chance for R1 (Minor) radio blackouts 27-26
Nov due to the combined potential of regions 2783, 2785, and 2786.
