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.

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.

R3 or greater    1%            1%            1%

Rationale
No R1 (Minor) or greater radio blackouts are expected. No significant active region flare activity is forecast.
Current data suggest that it is not possible to see aurora now at middle latitudes
