21-00UT        4          4          4     

Rationale: G1 (Minor) geomagnetic storms are expected on Apr 24 and
likely on Apr 25-26 due to the continued influence of a recurrent,
negative polarity coronal hole high speed 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 Apr 24-Apr 26 2017

              Apr 24  Apr 25  Apr 26
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 24-Apr 26 2017

              Apr 24        Apr 25        Apr 26
R1-R2            1%            1%            1%
R3 or greater    1%            1%            1%

Rationale: No R1 (Minor) or greater radio blackouts are expected.  No
significant active region flare activity is forecast.
