SpaceCom have updated the decay notice for the (Japanese) ETS-7 H2
rocket:
Object Notice issued Predicted decay
UTC UTC
#25065 = ETS-7 H2 r Jan 20 23:28 Jan 27 17:19 +-4d
-------------------------------
My current prediction for the ETS-7 H2 rocket is for its decay at
January 27.5 +-1.2 days. The latest elset is:
ETS-7 H2 r 13.5 2.5 0.0 3.0 v 267 x 244 km
1 25065U 97074C 99021.72024748 .00993266 00000-0 11778-2 0 4165
2 25065 34.5274 143.6430 0017170 294.0422 65.8959 16.07001711 65338
-------------------------------
As Harro has already reported in another thread, SpaceCom has released
the final elset for yesterday's decayer:
Irid 11A CZ r 10.0 3.0 0.0 3.5 d 137 x 105 km
1 25579U 98074C 99020.82028691 .30965950 -13023-5 11712-3 0 1373
2 25579 86.3364 181.2047 0024630 54.8491 305.6288 16.57138475 5104
I surmise that this decayed near, or possibly just north of, the
following northbound crossing of the equator at 21:08 UTC near 104
degrees east longitude - another one for the South China Sea which must
be filling up nicely :) This is a few minutes later than Harro's
estimate and a few minutes earlier than SpaceCom's.
