Notes:

66-  5 N
Not seen flashing again

71- 24 A
Dtm, very faint, but some flashes are mag 4

81-116 J 
Becomes dtm due to the long period

87- 11 A 
second obs was low in the northwest.

90- 78 B 
First obs was in the east, last obs in the west so better illuminated by the
sun, i.e. better phase-angle

91-  7 B 
On request by Kurt because of jump in MM. Was S last February, but now nice
flashing. To be followed if it is still accelerating, as it seems to do based on
these two obs.

92- 30 J
Acceleration stopped?

95- 58 B 
Is going up nicely, although bright still a bit dtm due to the somewhat
flat max

96- 29 D, C and E
Quite a sight the passage of this NOSS trio through the Pleiades. Time given is
when 96- 29 D passed just below star 23, the trailing sat passed this point 6.23
seconds later
 
96- 51 B
What a nice flasher. Sats like this one makes it worth to observe.

96- 71 A 
97- 71 B 
Both A and B are difficult to see. I missed first pass of 96- 71 B in the
east; second pass was in the west with a good phase-angle

Multiple observation
When I picked up 93- 55 C between Beta Corona Bor. and Delta Bootis a mag 7 steady
object moved just in front of it on the same track and speed. Just to the north of
these two objects another mag 7 steady object was seen, moving a little bit faster
and on a different track. The first two passed below Theta, Tau, Ypsilon Hercules
triangle and the other sat just above it. The last appeared to be 83- 04 A according
to the predictions. I'll try to identify the other faint sat using Skymap.
 
Shuttle/MIR
06:20
MIR was right on time, S mag 2 with in the east a flash of the solar panels
to mag 0.
06:36
About a minute late, according to the predictionmade with the TLE Mike McCants
provided yesterday, Atlantis showed up. STS-81 was S, mag 1 as it passed just
over Arcturus. Then the shuttle quickly faded and could not be seen even with
binoculars. Possible due to the phase-angle and/or orientation of the shuttle,
as it was flying towards the sun and I looked at the unlit backside.
Hope to see both again tomorrow morning when they have docked about one orbit
earlier.
