I have just updated my Decay Watch page at

with a prediction for #25761, the Raduga 104 aux motor, for which
SpaceCom has issued the first decay warning. I show decay at September 1
20:14 UTC +-15h, although SpaceCom has it 12 hours later. This object
was not even on my latest SatEvo decay list, the drag having increased
very sharply in the past few days as a result of the perigee being
forced lower - something I had not anticipated. I believe that this may
be observable in the evening from mid-northern latitudes as it moves
ESE-wards towards eclipse at about 20h local time near 40 deg N. The
prediction is very uncertain, though.
