For some reason, OIG is displaying a SpaceCom a decay notice for
Explorer 7 (#22 = 59- 9 A), predicting its decay for 2088 Feb 27 01:22
UTC +-2min. The latest elset for this is:
Explorer 7 0.8 0.8 0.0 8.8 d 0.85 828 x 518 km
1 00022U 59009A 00117.09478087 .00004047 00000-0 53767-3 0 4439
2 00022 50.3016 203.8141 0219626 347.3548 12.1933 14.66363024132550
Surely some mistake :)

concerning the actual current decayers...
#23834 = 96- 19 B = GPS 2-25 Delta 2 rocket
SpaceCom's latest estimate is for decay at Apr 27 12:33 +-15h at 20.3 N,
172.7 E, while I get Apr 27 13:36 +-6h near 25.0 S, 82.2 E. My estimate
places it northbound over the Indian Ocean as it nears the end of the
final predicted orbit:
GPS 2-25 r1 5.9 2.4 0.0 5.0 v 12 139 x 136 km
1 23834U 96019B 00118.51423213 .53556779 25539+1 55178-3 0 98635
2 23834 35.0295 183.9009 0002038 88.9389 271.0843 16.50693694228831
SpaceCom's places decay near the beginning of the same orbit, over the
Pacific Ocean. Between the two predictions, the rocket makes a pass
across the USA from the N of Los Angeles at 12:45 UTC to the S of
Houston at 12:50.
#26302 = 00- 21 B = Progress M1-2 Soyuz rocket
SpaceCom gives Apr 27 12:47 +-14h at 50.7 S, 35.5 E, while my prediction
is for decay at Apr 27 13:02 +-6h near a northbound equator crossing at
105.1 E. This is close to Singapore, Malaysia, at the end of the final
predicted orbit:
PrgM1-2 Soyuz r 6.0 3.0 0.0 5.0 d 15 140 x 129 km
1 26302U 00021B 00118.48302046 .46587496 18679+1 36107-3 0 90128
2 26302 51.6276 156.8634 0008300 90.2518 269.8433 16.52003543 274
Earlier that orbit, there is a pass across the USA from Seattle at 12:01
UTC to New Orleans at 12:09.
