An X1.5 flare (R3-Strong Radio Blackout) occurred on 10 May, 2022, at 9:55am EDT (1355 UTC). The flare was rather impulsive, so any high frequency (HF) communication impacts were likely short-lived and restricted to the sunlit side of Earth at the time of the flare – which was much of the Atlantic Ocean, portions of eastern North and South America, and western Africa and Europe. The source region for the flare was NOAA/SWPC Region 3006 – a moderately complex spot group in the southern solar hemisphere. Radio signatures associated with potential coronal mass ejections (CME) were observed and reported by the USAF with this activity – so a CME may be likely with this event; however, we await updated coronagraph imagery to confirm and analyze any CME.
