I had WSJT-X running just in case I had time to make a few QSOs while writing. There was plenty of activity and numerous decodes but I’d not had time to play. Then there was a cryptic decode at 16:09 UTC which just said ‘SOLAR FLARE’. The timing and frequency suggest it was someone a few squares away. And sure enough, no more decodes. At all. I switched to WSPR and recorded a couple of stations that way, and was recorded by a couple too, but it’s very dead. I wish I was watching the waterfall when it actually died off… anyway, not long after it seems to have recovered as I can see traces again and it’s decoding.
