We’ve had two more large solar flares already this morning, an X at around 0930 UTC and an M7 starting at about 1230 UTC that is still at M6 levels as I type this (1340 UTC).
The results are predictable, large fadeouts on HF, especially the lower frequencies. 31 meters is a graveyard, with very few signals, all weak. I am hearing China on 9845, probably because the path to the west of me is mostly in darkness still.
CFRX 6070, which is usually S9+, is about S3, with many deeper fades.
Update: There’s been some more flares today, with an M3.1 just peaking now, at 1730 UTC.
