A. NOAA Geomagnetic Activity Observation and Forecast
The greatest observed 3 hr Kp over the past 24 hours was 5 (NOAA Scale
G1).
The greatest expected 3 hr Kp for Dec 30-Jan 01 2015 is 4 (below NOAA
Scale levels).

Rationale: G1 (Minor) geomagnetic storms are likely due to continued
effects from a coronal hole high speed stream.
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 Dec 30-Jan 01 2015
Dec 30 Dec 31 Jan 01
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.

Dec 30 Dec 31 Jan 01
R1-R2 20% 20% 20%
R3 or greater 1% 1% 1%
Rationale: A slight chance for R1-R2 (Minor-Moderate) radio blackouts
exists due to flare potential from Region 2251 (S09E25).
