At first there were some clouds. 98- 43 G was observed in a cloudless part
of the sky, but 93- 61 A in between clouds.
Then it became almost cloudless.

Nice flasher. Latest PPAS obs shows it at 8.8. sec in april 98. Was
around 1 sec back in 75.

93- 61 A 99-05-11 20:51:27   LB   28.4 0.5   4  7.1   AA, 3->inv, N?, clouds
Is half period. Was 14.22 May 03

96- 17 B 99-05-11 21:17      LB                       S, mag 6
98-  7 D 99-05-11 21:11      LB                       almost S, mag 6
98- 43 G 99-05-11 20:42:20   LB  199.9 0.5   5 40.0   AA, mag 2->6
Going up slowly

99- 19 E 99-05-11 21:32:18   LB   83.5 0.2  20  4.17  'Fff-'F, mag 2(3)->inv
Nice flasher, easy to time on the bright flash after the 'missing' flash
Looks a lot like 99- 12 E that launched the previous set of Globalstars

99- 19 F 99-05-11 21:42      LB                       S, mag 5, ID?:99 -19
B?
Although based on TLE from day 106 it was right on time. The 99 -19 B object

made a pass in the same track about 30 sec earlier based on TLE from day
127.
But only one object was seen. It could have been 19 B as OIG listed 19 F as
decayed when I looked for TLE's.

99- 20 B 99-05-11 21:03:22   LB    9.8 0.5   2  4.9   fl in NE -> almost S,
3
When first spotted it was flashing on this low pass in the east, but became
almost S more to the north.


A few days ago Kurt Dequick reported a unknown which was flashing at 4.08
sec.
Using my recent TLE-file I got a perfect fit for 99- 19 E on 990508 at 21:53
UT.
So Kurt must have seen this sat and not 96- 17 B as reported before. Was
also
may 09 as Kurt reported the day wrong.
