The final published elset for this is
SL-12 r (aux motor)                              555 x 80 km
1 24454U 96058E   97207.02243057  .99999999  67311-5  89173-3 0  3085
2 24454  46.7417 152.1610 0354482 128.4484 235.3926 15.84693647  8745
showing it running 83 seconds early against the SatEvo prediction.

I do not think it could have survived the subsequent perigee pass at
July 26.044 (01:03 UTC) which is my estimated time of decay. At that
time it would have been ESE-bound over the Atlantic, to the SW of the
Azores, having crossed roughly from Los Angeles to Quebec between 00:45
and 00:55 UTC.
