I wonder if the high latitude figures affect transequatorial propagation on
Topband. I doubt it. The Boulder figures have proved almost useless for
that path as well, EXCEPT when the A index rises sharply from a low value,
as it did early Friday morning. Then we also had excellent propagation to
the US. This has happened before.
On the suggestion of N4XX, I am trying to correlate good condx with the
measured xray counts from the GOES satellites, assuming that the D layer
absorption is affected. No real correlation yet that I can see. What was
missing in the 6 hours preceding Friday SR were the short term excursions
into the high C values (Xrays)
