Observations August 7-8, 1997

Last night was another splendid night for observing.
The weather was very good, cloudless, no haze and good temperatures of 20
to 16 degrees Celsius.

This afternoon I watched on CNN the launch of the shuttle Discovery and the
docking of Soyuz TM 26 with MIR.

The night started with Cosmos 2342 rocket (97- 22 B) zipping across the sky.
Only the brightest stars were visible at 19:56 UT when I spotted 97-22 B about 
10 degrees north of the predicted path, calculated by using Alan's prediction 
TLE with Epoch 97219.81986284. The sat was on time and the different path not so
remarkable given the extreme height of only 137 km. Must have seen this sat on 
(one of) its last orbit(s).

A few minutes later, at 20:07 UT, MIR made a high pass. MIR was steady mag -1.
I didn't see the Progress, according to predictions it was some 10 seconds 
before MIR.
The next orbit I spotted MIR at 21:43 UT as it popped up from behind the roof
of my house.
No Progress in front of it, but it was BEHIND the MIR. 97- 33 A trailed MIR
by 27.35 seconds. Progress probably made a small orbit correction.
MIR was S, mag -1 and Progress M 35 was S, mag 2.
 
Observed two of the recently launched Iridiumsats. 97- 34 A was bright and
steady mag 3; 97- 34 E just visible at mag 6 and steady. The Delta 2 rocket
that launched these sats, 97- 34 F, was also bright at mag 3 and variable
with small amplitude.
