Apparently Leo has found STEX after it has been lost
for about 3 years.  Of course the mean motion is quite uncertain.
It could be off 1 or 2 minutes per day.

Let me explain things.
I wasn´t searching for 25489. The sat passed by while waiting for another
sat.

The residuals didn´t trigger me.

Very low residuals on TLE from 2012. The age of the TLE should be around
1060 days.

Did try observe 25489 on the next nights.
The sat didn´t show up on the images.
First night I used the old TLE, the next night Mike´s new TLE.

Will try again this night.

I could be that my obs from 28 Sep were bright background pixels.

Sorry for any inconvieniance.

Regards
Leo
