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 Jan 05-Jan 07 2015 is 5 (NOAA Scale
G1).

NOAA Kp index breakdown Jan 05-Jan 07 2015

            Jan 05     Jan 06     Jan 07
00-03UT        5 (G1)     4          3     
03-06UT        3          3          2     
06-09UT        3          2          2     
09-12UT        2          2          2     
12-15UT        3          2          2     
15-18UT        3          2          2     
18-21UT        3          2          2     
21-00UT        4          3          2     

Rationale: There is a slight chance for G1 (Minor) or greater geomagnetic storms on days one and two Jan 05-06 in response to a high speed solar wind 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 Jan 05-Jan 07 2015

              Jan 05  Jan 06  Jan 07
S1 or greater    5%     10%     10%

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

Radio blackouts reaching the R1 levels were observed over the past 24 hours. The largest was at Jan 04 2015 1536 UTC

Radio Blackout Forecast for Jan 05-Jan 07 2015

              Jan 05        Jan 06        Jan 07
R1-R2           50%           50%           50%
R3 or greater  10%          10%          10%

Rationale: There is a continued chance for R1 (Minor) or greater radio blackouts from Region 2253 from Jan 05 to Jan 07.
