Hi Richard,
That's somewhat common.
We Greenman's station was 10 miles due east of mine.? We would often see
completely different patterns during Jovian DAM events, even in the middle of
the night when the F layer is thought to be rather quiescent.? And we would
equally often see no differences.
I think seeing differences in observed scintillation on a relatively short 10
mile baseline indicates that they're due more to ionospheric dynamics than the
dynamics of the IPM.? However, that's only a guess based on a gut feeling about
the geometry and distances involved; I have no math to back that up.
