Hi Kevin,
Great video again.
Norad 10637 is 1978-12 A or IUE-1, International Ultraviolet Explorer.
This is what I have on this launch in the Revised RAE tables of Earth
satellites on my homepage.

In PPAS I found thiese entries:
78- 12 A 98-03-25 05:16 RIK 60 1.0 14 4.3 F'FF_F', mag 11
78- 12 A 98-05-26 06:45 RIK 122.0 1.0 28 4.36 f'ff_f', mag 12
78- 12 C 97-08-04 MM 15.8 v2,wow
78- 12 C 97-08-28 MM 16 v3
I don't know who RIK is, but MM is Mike McCants.
So when Kevin took this video is was at quite a distance, between 30000 and
40000 km above the earth.
Perhaps Kevin can give us the brightness of the star(s) in the field to make
an estimate of how bright the flashes were.
I've timed the flashes from the video with my stopwatch; better would be to
use the timestamps on the video, but I
don't have the proper program to view it picture by picture.
I got: 4.31 4.46 4.43 4.46 4.43 sec; this gives a period of 4.42 sec.
In the 8 years since RIK observed it it hasn't got up much.
The perigeemotor can also be bright as Mike has reported.
It now has (still) a low perigee.
Greetings and clear, dark skies
