My Decay Watch page enjoyed several updates while SeeSat was AWOL. A
summary of the latest follows.
Also note that my latest SatEvo Decay List (#127) was issued on the
17th, see:

Object: #21990 = 92- 32 B = Intelsat 101 Atlas Centaur rocket
Decay predictions:
Source Prediction made Predicted decay at Latitude Longitude
UTC UTC deg deg
SpaceCom May 21 11:10 May 28 11:21 +-4d 11.8 S 98.1 E
SatEvo May 21 18:35 May 29 14:28 +-3d
Latest elset:

SatEvo prediction: See Decay Watch page.
Note: This enters eclipse while southbound near the equator in the
evening . Eclipse exit occurs before dawn as this heads northwards
near 17 deg S.

Object: #24780 = 97- 18 B = Celestis
Final analyses:
Source Prediction made Predicted decay at Latitude Longitude
UTC UTC deg deg
SpaceCom May 20 20:05 May 20 08:58 +-1m 24.7 S 74.2 W
SatEvo May 20 19:00 May 20 09:35 +-80m 22.3 N 104.1 E
Final elset:
Celestis 1.3 1.0 0.0 7.5 d 1.8 169 x 163 km
1 24780U 97018B 02140.14848978 .15486369 -41423-4 10900-2 0 963
2 24780 150.9437 170.8721 0004795 298.1029 62.0265 16.39819236281329
Note: I have this decaying over southern China a little beyond
the end of the following SatEvo-predicted rev:
Celestis 1.3 1.0 0.0 7.5 d 1.8 136 x 133 km
1 24780U 97018B 02140.33050161 .84317711 98926+1 71279-3 0 90964
2 24780 150.9417 172.3312 0002418 300.4568 59.5192 16.51833144281356
This is about six hours after the final elset, so the uncertainty
(except for SpaceCom, apparently) remains high.
