R1/R2 Radio Blackouts on 19 May 2022
published: Saturday, May 21, 2022 17:13 UTC

In the past 24 hours, NOAA SWPC Region 3014 has produced several R1 (Minor) radio blackouts, as well as an R2 (Moderate) radio blackout. The R2 radio blackout was the result of an M5 flare that occurred on 19 May 2022 at approx 19/0719 UTC (0319 EDT) from an area between Region 3014 and Region 3017. The most recent activity was an M1 flare (R1-Minor) that occurred at approx. 19/1521 UTC (1121 EDT). Forecasters are currently analyzing available satellite imagery to determine if any coronal mass ejections (CMEs) were associated with the flares, and if any of the CMEs have an Earthward trajectory.  Stay tuned here and on our website for updated information.
