On a warm summernight it is a nice hobby we have!!

MIR and Progress
================
Timed the passage of MIR and Progress-M 35 when they passed between Iota
Ophiuchus and 43 Hercules.
MIR at 21:05:21.96 and 103.07 seconds later followed by Progress.
So the time difference has increased again by 103.07-80.15= 22.92 seconds.
My timing of yesterday could have been wrong and Alex Seidell was right, but then 
the difference is now 103.07-84.4= 18.7 seconds.
So Progress did manoeuvre one way or the other.

Very nice view indeed, Jim. The flashes were not constant in magnitude
and varied between 4 and 6.

When I picked up the sat in the south it was very rapidly flashing like
EGP 86- 61 A; with one flash brighter. Later in the pass the bright flash
was clearly visible and measurable.

This Long March 3A rocket in GTO was at a height of 5700 km, range much more.
It was very good visible. Last PPAS entry is a bit off; this obs confirms
the other two entries and it didn't change much.
