Hi Bill,

This morning I noticed that my old main suspect US beacons, K5AB had made 4 appearances yesterday at 0200z +/-.

That has not happened for a long long time.

What caught my attention iS the time nature of the solar flux is the slow rise and fall with peaks in-between. It took a whole day to rise and another day to decline.
I have not seen this before, or at least, I can't recall.

Hi Dieter – By my count, there have been at least six M-class events in the past 24-hours.  That large sunspot is throwing them out left and right.

It should be interesting to see what effect they will have on 10m.

Wow - this is: BIG.

Usually, solar flares peak into the M region of X-ray flux density but this is something else I have not seen before. Wonder if anyone notices a change on 10m? Might be a delayed change.
