NOAA Forecasts Potential Radio Blackouts from Sunspot Activity

The NOAA Space Weather Prediction Center has issued an outlook warning of potential R1-R2 (Minor-Moderate) radio blackouts from May 25-31. This forecast is attributed to the flare potential of old sunspot Region 4432, which is expected to rotate onto the visible solar disk around May 25.

Previously, R1 (Minor) radio blackouts were observed on May 22, caused by flare activity originating from sunspot region 4436. These events can impact high-frequency radio communications.

The advisory, issued from Boulder, Colorado, highlights ongoing space weather activity. Data for these services are contributed by various organizations including NOAA, USAF, NASA, and international partners.
