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 Apr 16-Apr 18 2014 is 3 (below NOAA
Scale levels).
NOAA Kp index breakdown Apr 16-Apr 18 2014
Apr 16 Apr 17 Apr 18
00-03UT 1 2 3
03-06UT 1 2 2
06-09UT 1 2 2
09-12UT 2 2 2
12-15UT 2 1 1
15-18UT 1 1 1
18-21UT 1 2 2
21-00UT 2 3 3
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 Apr 16-Apr 18 2014
Apr 16 Apr 17 Apr 18
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.
Radio Blackout Forecast for Apr 16-Apr 18 2014
Apr 16 Apr 17 Apr 18
R1-R2 60% 60% 60%
R3 or greater 10% 10% 10%
Rationale: Solar activity is likely to be at (R1-Minor) levels for the
next three days (16 - 18 Apr) as Regions 2034, 2035, 2036, and 2037
maintain increased magnetic complexities.
