21-00UT        2          2          5 (G1)

Rationale: G1 (Minor) geomagnetic storm levels are likely late on day
three (24 Oct) due to recurrent CH HSS effects.

B. NOAA Solar Radiation Activity Observation and Forecast

Solar radiation, as observed by NOAA GOES-13 over the past 24 hours, was
below S-scale storm level thresholds.

Solar Radiation Storm Forecast for Oct 22-Oct 24 2017

              Oct 22  Oct 23  Oct 24
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 Oct 22-Oct 24 2017

              Oct 22        Oct 23        Oct 24
R1-R2           20%           20%           20%
R3 or greater    1%            1%            1%

Rationale: There is a slight chance for M-class flares (R1-R2,
Minor-Moderate) over the next three days (22-24 Oct) due to flare
potential from Region 2685.
