Scale levels).
The greatest expected 3 hr Kp for Nov 27-Nov 29 2014 is 3 (below NOAA
Scale levels).

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.
