Hi Lew,

How about a date and time? I can't always get onto the internet - problem
with being at the end of the line in a third world country!

I had an abbreviated run from Aug 26.35-26.41 UT. The measures were bounded
by two eclipses - I saw half of each - but it appeared to be rising during
the 80 minutes or so. Perhaps 5%. About where it was on 22 Aug.

Regards,
Stan
