21-00UT        4          5 (G1)     6 (G2)

G1 (Minor) geomagnetic storms are likely on day two (27 Mar) with G1 (Minor) and G2 (Moderate) levels likely on day thee (28 Mar) due to coronal hole high speed stream activity.

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 Mar 26-Mar 28 2017

              Mar 26  Mar 27  Mar 28
S1 or greater    1%      1%      1%

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 Mar 26-Mar 28 2017

              Mar 26        Mar 27        Mar 28
R1-R2            1%            1%            1%
R3 or greater    1%            1%            1%

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
