foF2 was up above 7 MHz for a while, this often happen just as a geomagnetic storm is starting, the K index was 4.

When I see a blip like that at ~0620 UT, my first inclination is to think that it is not authentic (i.e., bad data) and some quirk of reception happened or the algorithm that determines FoF2 from the ionosonde data was "fooled" somehow. That data point is too weirdly out of place, even though FoF2 did appear to be slightly elevated that day compared to other recent days.

Sorry, I was referring to the extended period above 7 MHz the day before, so the red trace on the right side of the graph.  The circa 0620 UTC blip is certainly just bad data.

Speaking of propagation, there was a nice opening on 40m yesterday afternoon, for a short period of time the CW portion was wall to wall signals.

Now it I could only get my peak audience to coincide with the peak propagation...  Ah the majik of Radio

Oh. OK. I misunderstood.
