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 17-Nov 19 2024

              Nov 17  Nov 18  Nov 19
S1 or greater   10%     10%     10%

Rationale: There is a slight chance for the greater than 10 MeV proton
flux to reach S1 (Minor) levels over 17-19 Nov.

C. NOAA Radio Blackout Activity and Forecast

No radio blackouts were observed over the past 24 hours.

Radio Blackout Forecast for Nov 17-Nov 19 2024

              Nov 17        Nov 18        Nov 19
R1-R2           45%           45%           45%
R3 or greater   10%           10%           10%

Rationale: A chance for R1-2 (Minor-Moderate) radio blackouts will
persist through 19 Nov along with a slight chance for an R3 (Strong) or
great event.
