SPACE WEATHER ADVISORY OUTLOOK #15-2
2015 January 11 at 10:15 p.m. MST (2015 January 12 0515 UTC)

**** SPACE WEATHER OUTLOOK ****

Summary For January 5-11

G1 (Minor) geomagnetic storming was observed on 05 January due to coronal hole high speed stream activity.

G2 (Moderate) to G3 (Strong) geomagnetic storming was observed on 07 January due to activity possibly associated with a co-rotating interaction region coupled with a coronal mass ejection.

Outlook For January 12-18

A chance exists for R1-R2 (Minor-Moderate) radio blackouts for the forecast period due to potential flare activity from Regions 2255 or 2257 along with the return of old Region 2249.

A. NOAA Geomagnetic Activity Observation and Forecast

The greatest observed 3 hr Kp over the past 24 hours was 2 (below NOAA
Scale levels).
The greatest expected 3 hr Kp for Jan 12-Jan 14 2015 is 3 (below NOAA
Scale levels).

21-00UT        3          2          2     

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 Jan 12-Jan 14 2015

              Jan 12  Jan 13  Jan 14
S1 or greater    5%      5%      5%

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 Jan 12-Jan 14 2015

              Jan 12        Jan 13        Jan 14
R1-R2           40%           40%           40%
R3 or greater   10%           10%           10%

Rationale: There is a chance for an M-class flare (R1-R2/Minor-Moderate)
and a slight chance for an X-class flare (R3-Strong) mainly from Regions
2257, 2259 and 2260 during the next three days (12-14 Jan).
