...now at 22:50 the ripples are weaker,
and the multipath seems to have moved to a positive frequency
offset. There is a delay-vs-Doppler
analysis of a similar but stronger event in Feb 2006 on
Maybe there is some relation to Warren's
Doppler spread observation a couple of weeks ago:

Subject: LF: SXV ripples again
a rare and remarkable selective fading
effect on SXV is currently visible on the LF grabber http://members.aol.com/df6nm/Grabber.htm .
The period and slant of the colour ripples seem to indicate a second
component, which is currently Doppler shifted by -0.05 Hz and delayed by
about 5 milliseconds. Still lacking an explanation...
