University of Alberta AuroraWatch
When the aurora is active, ICEBEAR tends to see more action too.

NOAA 3-Day Space Weather Forecast
The below forecast was prepared by NOAA to predict geomagnetic activity, solar radiation, and radio blackouts, all of which effect ICEBEAR operations.
:Product: 3-Day Forecast :Issued: 2026 Apr 20 1230 UTC # Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center # A. NOAA Geomagnetic Activity Observation and Forecast The greatest observed 3 hr Kp over the past 24 hours was 4 (below NOAA Scale levels). The greatest expected 3 hr Kp for Apr 20-Apr 22 2026 is 4.00 (below NOAA Scale levels). NOAA Kp index breakdown Apr 20-Apr 22 2026 Apr 20 Apr 21 Apr 22 00-03UT 0.67 3.33 2.67 03-06UT 2.33 4.00 2.00 06-09UT 4.00 3.00 2.33 09-12UT 3.67 2.67 2.00 12-15UT 3.67 2.33 2.00 15-18UT 3.00 3.00 2.33 18-21UT 3.00 2.67 2.00 21-00UT 2.67 2.33 2.00 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-18 over the past 24 hours, was below S-scale storm level thresholds. Solar Radiation Storm Forecast for Apr 20-Apr 22 2026 Apr 20 Apr 21 Apr 22 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 20-Apr 22 2026 Apr 20 Apr 21 Apr 22 R1-R2 5% 5% 10% R3 or greater 1% 1% 1% Rationale: No R1 (Minor) or greater radio blackouts are expected. No significant active region flare activity is forecast.
