Apologies : A serious mistake is that the times (02:36-02:37) should be
0036 to 0037. And the ID should be 14612A
But I used the correct zone in my analysis.
I forgot to mention that the second point is measured at the edge of an
image, so the time is a guess by a few seconds.

Two more images of #39287 were found as UNID, and one (preceding) image of
the unid 14 612 A.
I was too eager to move the camera, so only the initial point is measured.
Now 19 images of 48 have 11 identified satellites, three have 14612A, 8
have 12 UNIDs (but not all unique?)

00000 14 612A   5919 E 20140422003614000 18 25 1402950+341689 55 S
Corrected:
00000 14 612A   5919 E 20140422003641000 18 25 1224356+521941 55 S

00000 14 612A   5919 E 20140422003715000 18 25 0924699+595807 55 S
