Ekki,
I believe the data was X-radiation energy that I saw on the chart and it
will propagate comparable to any shorter wavelength EM wave (ie: up to light
speed). The X-ray impact on our propagation paths is what you observed so
quickly. I did not see any mention of any CME from this area (yet) but you
are quite correct in saying there would be a delay in earth impact from that
sort of mass ejection.
Nice to hear you had a good score :-)) Sorry to have missed the last
contests but I am presently attending to family needs and not QRV from home.
73 and hope to meet you in CQ/RJ WW.
George .. W1ZT
