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 Oct 26-Oct 28 2014 is 4 (below NOAA
Scale levels).

21-00UT        3          3          3

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-13 over the past 24 hours, was
below S-scale storm level thresholds.

Solar Radiation Storm Forecast for Oct 26-Oct 28 2014

              Oct 26  Oct 27  Oct 28
S1 or greater   35%     40%     45%

Rationale: There is a chance for a greater than 10 MeV proton flux event
at or above the S1 (Minor) solar radiation storm level for the next
three days.

C. NOAA Radio Blackout Activity and Forecast

Radio blackouts reaching the R3 levels were observed over the past 24
hours. The largest was at Oct 25 2014 1708 UTC

Radio Blackout Forecast for Oct 26-Oct 28 2014

              Oct 26        Oct 27        Oct 28
R1-R2           85%           85%           85%
R3 or greater   45%           45%           45%

Rationale: R1-R2 (Minor-Moderate) radio blackouts are expected over the
next three days (26-28 Oct) with a chance for R3 (Strong) or greater
radio blackouts.
