#17256 = 81- 58 E = Cosmos 1278 deb
According to SpaceCom, this debris object has a Radar Cross Section of
2.5 m^2, which presumably is why decay warnings have started to appear.
It enters eclipse while southbound near 35 deg N at ~02:00 local time
and leaves eclipse still southbound near 47 deg S at ~06:00 local time.
Current decay predictions:
SpaceCom: Jul 7 03:34 +-2d 18.0 N 174.2 W
SatEvo: Jul 7 00:52 +-20h
Latest elset:
Cosmos 1278 deb E 3772 x 108 km

#20339 = 89- 94 B = Molniya 3-36 r
This is down at last...final decay analyses:
SpaceCom: Jul 4 03:35 +-32m 4.5 N 18.5 E
SatEvo: Jul 4 03:14 -15m+90m 57.4 S 29.4 W
The final elset...
Molniya 3-36 r 296 x 75 km
1 20339U 89094B 00186.11250000 .99999999 75412-5 28885-3 0 611

...has this 57 sec late against my last
prediction. I put decay a little beyond perigee on this orbit, over
the South Sandwich Islands in the South Atlantic. It is possible
that it survived to re-enter near perigee on the following orbit at
about 04:33 UTC near 60.5 S, 118.8 W, over the SE Pacific.
