The latest elsets from OIG for the decaying Soyuz rocket and the
associated C object are:
Soyuz TM-26 r                                    188 x 170 km
1 24887U 97038B   97219.66590038  .04084347  12292-4  49932-3 0   149

Soyuz TM-26 deb                                  222 x 169 km
1 24888U 97038C   97219.24678963  .08698103  12165-4  15600-2 0   203
2 24888  51.6098 189.2396 0040438  83.4272 276.8999 16.29030627   268
These are respectively 32 and 29 seconds early as compared with the
SatEvo predictions I posted yesterday.

The rocket, 97- 38 B, is now predicted to decay around August 8.6.
Here are some predicted elsets:
Soyuz TM-26 r                                    183 x 166 km

I suspect the "debris" object, 97- 38 C, has decayed already at about
August 7.69. My final predicted elset is:
Soyuz TM-26 deb                                  154 x 139 km
1 24888U 97038C   97219.67445418  .71602905  60047+1  11754-2 0 90148
2 24888  51.5993 186.8423 0011389  82.9361 277.1934 16.47222378   338

I post the latest OIG elsets for all decayers, other selected objects
and new launches (including STS-85), on my SatEvo WWW page (URL below)
every three hours.
