The decaying Cosmos 2351 objects, #25328 and #25329, may decay about
June 12 and May 29 respectively according to my initial SatEvo
calculations. At present, they enter the Earth's shadow near latitude 40
deg S during local evening and exit eclipse at about 9 deg S during
local mornings.
I believe that #25333, the Echostar 4 Proton platform, has already
decayed at about May 8.69 (~16:30 UTC).
The Proton itself, #25332, may last until May 10.1 +-0.4d. It enters
eclipse at about 52 deg S latitude during local evening and exits at
around 44 deg N latitude in the morning sky. Predicted elsets:
