北京时间2022年4月30日21:39发生X级耀斑，于21:51结束，级别为X1.1级。该耀斑由已转出可视日面的活动区AR2994产生，并伴随有偏晕日冕物质抛射（CME）。此外，该活动区还产生了多个M级耀斑。
Region 2994 (N15, L=107) produced an impulsive X1 flare at 1347 UTC on 30 April 2022. Radio degradation was possible in sunlit locations, with the possibility for temporary radio blackouts over the Atlantic Ocean during the time of the event. Region 2994 is beyond the west limb and the associated CME is not expected to be Earth-directed.
