This object was also observed by Koen Geukens as mentioned by Tristan:

Thanks to this elset Alan posted (from OIG)

I could predict it for my location to have passed over there around 21h25m,
with a path that is fitting very well with our observation. (although 5  
minutes too late).
I did not saw anything around 21h25m.

So I'm rather sure that after about 10 years of observing I finally saw
my first DECAY !  
BUT, I did NOT saw 97- 38 C, because it was still up around that time
which is acknowledged by OIG's elset of this morning (after my decay
observation) : 
24888
1 24888U 97038C   97219.24678963  .08698103  12165-4  15600-2 0   203
2 24888  51.6098 189.2396 0040438  83.4272 276.8999 16.29030627   268

So the question about what object we saw still remains, maybe it was
another piece of debris that broke off 97-38 C (heavy speculating...) ?
