...and later OIG published these:

and I waited for more but none came :-(
Forcing a SatEvo evolution through the equator crossings for the elsets
for 97075.69, 97075.76 and 97075.83 yielded the following:

This suggests that it should survived the perigee at March 16.95. Decay
probably occurred near the next perigee over the S Central Pacific at
about March 17.017 (00.25 UTC)
