SatEvo decay list #7 (issued 1996 June 8)
Here are my updated SatEvo decay predictions. The "Actual?"
decay times are estimated from the final available elements.
# Designation Name ------ Decay ------
Predicted Actual?
23684 95- 54 E SL-12 R aux motor May 20.2
23882 96- 34 C SL-12 R platform May 26.1
13786 83- 6 B N-2 R1 May 27.05
23459 94- 87 E SL-12 R aux motor May 27.15
23881 96- 34 B SL-12 R May 28.4
18978 63- 14 DR West Ford Needles deb May 31.1
2950 63- 14 AT West Ford Needles deb June 3.8
23660 95- 45 E SL-12 R aux motor (see note) June 6.55
23889 86- 17 KH GFZ 1 deb June 12.2
20042 89- 41 C Ariane 44L R June 13.0
23462 95- 1 B Atlas 2AS Cent R June 20
23583 95- 20 C Progress-M 27 deb June 25
23508 95- 8 D Cosmos 2306 deb June 30
23024 94- 14 F SL-14 deb July 7
11762 80- 28 E SL-6 R2 July 8
23557 86- 17 JD GFZ 1 deb July 14
18277 71- 3 C SL-3 deb July 28
Note 1: NASA are predicting the decay of #22854 = 89- 89 AR (COBE deb)
for July 23. However, the latest element available from OIG
for this object is almost 2 years old.
Note 2: Unusually (uniquely?) the final OIG element for this object
has an ndot (MMDOT) value greater than the usual ceiling of
.99999999:
95- 45 E
