Ed Cannon and I were able to watch 75-43A (DMSP 7) for about
1 minute this evening.  It varied in brightness from about 6 to 9.
The period was 30 seconds or so.  It was within a couple of seconds
of my previous elset, but it was about 1/2 degree east of the
predicted position.

I obtained the following positions:

30.3138N  97.8661W  920 ft   Bee Caves Rsrch Ctr (Austin, Tx)

I have derived the following elset:
