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.

C. NOAA Radio Blackout Activity and Forecast
Radio blackouts reaching the R1 levels were observed over the past 24
hours. The largest was at Dec 14 2014 1933 UTC

SPACE WEATHER ADVISORY OUTLOOK #14-50
2014 December 14 at 6:55 p.m. MST (2014 December 15 0155 UTC)
**** SPACE WEATHER OUTLOOK ****
Summary For December 8-14
A G1 (minor) geomagnetic storm was observed on 12 December.
R1 (minor) radio blackouts were observed on 13 and 14 December.
No S1 (minor) or greater space radiation events were observed, although 10 MeV proton flux at geosynchronous orbit was enhanced on 14 December, with a maximum flux of 2.5 pfu.
Outlook For December 15-21
R1 or greater radio blackouts are possible throughout the forecast period.
There is a chance for G1 (minor) storm conditions on 28 Dec through 09 Jan in response to recurrent high speed solar wind features.
There is a slight chance for an S1 (minor) or greater space radiation event through the forecast period.
