ISS visible pass

ISS made a nice visible pass this evening, before entering eclipse at about
11:52 PM CDT.

I would estimate about a magnitude 1 or 2 (brighter than Mars, less than
Venus) - be interesting to see if this changes as new solar array is
unfurled and then allowed to rotate toward sun.

Did not see any flash, more like a "double twinkle" at eclipse line

Another good ISS pass this evening (July 17) at about 10:25 CDT -- maximum
elevation (locally) was 60 degrees. Just short of the maximum elevation,
ISS increased significantly in brightness (definitely brighter than Venus
! ) -- brightest I have ever seen it (- 3 or - 4 ??).
Appeared to be result of solar array alignment on this pass -- about 30
seconds later it slowly started to drop

Another beautiful pass of ISS-Alpha and the STS-117 Atlantis trailing it
(that was the bonus!) tonight.

July 19, 10:05 PM MDT from Northern New Mexico. Very nice with ISS
leading and STS following.

It went behind clouds shortly after it began fading, so I dan't speak
to flash vs. twinkle.

Clearly visible from Toronto, too, from the grounds of the Aerospace
Museum (we happened to be there for a meeting, so we stuck around for the
pass). We got a brief flare from Atlantis, presumably a radiator glint.
Shadow entry was behind some thin cloud, so can't comment on that.
