I have just updated my Decay Watch page at
http://www.wingar.demon.co.uk/satevo/dkwatch/
with more on the following...
#20339 = 89- 94 B = Molniya 3-36 r
Current decay estimates:
SpaceCom: Jun 30 14:38 +-14h 47.0 S 77.2 E
SatEvo: Ju1 1 04:15 +-5h 62.7 S 54.0 W
The latest elset:
Molniya 3-36 r 1721 x 87 km
1 20339U 89094B 00182.78761690 .33245410 14503-4 41091-3 0 383
2 20339 63.7520 2.7616 1122087 246.1392 116.5958 13.97189766 76861
SpaceCom is still having fun with this decay, though the elsets no
longer show their wild fluctuation. The latest elset has this running
all of 12 minutes late against yesterday's prediction, though this is
over an interval in which the orbital period had fallen from 122 minutes
to 103 minutes. My predicted elset for the final revs...
Molniya 3-36 r 985 x 82 km
1 20339U 89094B 00183.06186221 2.89622085 36612+1 20759-2 0 90383
2 20339 63.7077 1.9195 0653141 246.1197 106.9026 15.10819189 76903
Molniya 3-36 r 722 x 81 km
1 20339U 89094B 00183.12749866 4.09138095 10511+2 22348-2 0 90384
2 20339 63.6896 1.6921 0472668 246.1150 108.8620 15.55394584 76915
Molniya 3-36 r 272 x 75 km
1 20339U 89094B 00183.19105666 9.99999999 50000+2 32096-2 0 90385

... with decay most likely near perigee in the second of these.

#21025 = 90-112 F = Raduga 26 aux motor
Current decay estimates:
SpaceCom: Jul 1 20:40 +-22h 15.8 N 133.0 E
SatEvo: Jul 2 03:45 +-9h 20.8 N 119.7 W
Latest elset:
Raduga 26 aux motor 942 x 122 km
1 21025U 90112F 00182.57336730 .19999469 99832-5 88992-3 0 5456
2 21025 46.3399 204.7679 0592651 33.6317 104.2548 15.11394986131301
The latest elset shows this running 3.4 minutes early against
yesterday's SatEvo prediction - the prediction had been badly upset by
the too-high eccentricity in yesterday's "latest" elset. It is early
days, but it is possible that this could decay on a northbound pass
across N America from Las Cruces, New Mexico, at 03:49 UTC on the 2nd to
Montreal at 03:56. My predicted final elset:
Raduga 26 aux motor 287 x 107 km
1 21025U 90112F 00184.09040338 1.28619534 40068+1 11813-2 0 95452
2 21025 46.3054 196.2983 0136967 42.1211 318.9237 16.28336008131549
with decay soon after the end of this rev.
