X1 Flare (R3 - Strong Radio Blackout) on 30 March, 2022

R3 Event on 30 March, 2022
X1 Flare (R3 - Strong Radio Blackout) on 30 March, 2022
published: Friday, April 01, 2022 14:40 UTC

An X1 flare (R3 - Strong Radio Blackout) occurred at 1:37 pm EDT (1737 UTC) March 30th, 2022. The flare source location was from the magnetically complex sunspot group, Region 2975. Initial indications are this flare was associated with a new coronal mass ejection (CME) and SWPC forecasters are currently examining data to confirm any CME, and if verified, analyze further to determine whether there may be any Earth-directed component. This same sunspot group has been the source of multiple M-class flares (R1 - Minor) over the past few days, with the strongest prior flare being an M4 at 28/1129 UTC.
