#20496 = 90- 15 A = LACE (USA 51)
SpaceCom's latest decay warning, issued at May 22 02:24 UTC, predicts
this decay for May 24 19:42 +-2d at 40.1 S, 148.6 W. Still, though, no
fresh elsets have been published for this.
As usual, the SpaceCom prediction includes a "trajectory prior to decay"
and I have tried to link this, and the one from the previous prediction,
with a much earlier elset for LACE. The result is the following very
uncertain prediction, which might form the basis of a search:

This enters eclipse while northbound just to the N of equator at ~19:00
local time and leaves eclipse while southbound near 30 deg N at ~03:30
local time. Unfortunately for observers in the S USA, this latter point
is shifting rapidly southwards from day to day.
