The final notice for the Integral Proton casing, plus the initial ones
for two more decayers. Following discussions on the List, and in
particular Harro Zimmer's suggestion, I am switching with these new
objects to identifying the source of the "official" decay estimates as
the SCC (Space Control Center). As my Decay Watch page now indicates,
this is a component of the US Strategic Command, USSTRATCOM.

Note: This enters eclipse northbound near 61 deg S at ~01:30 local
time. Eclipse exit occurs southbound near 83 deg N.

SatEvo prediction: See Decay Watch page.
Note: Eclipse entry occurs southbound near 19 deg N in the evening,
with eclipse exit just after southern apex at 30 deg S before dawn.
There is quite a discrepancy between the SCC (Space Control Center)
and SatEvo decay estimates.

Note: I estimate that this decayed soon after the end of the above
orbit, northbound over eastern Cuba and the Bahamas.
