[amsat-bb] UO-22 just 100000 on 3rd Aug 2010

[Mineo Wakita]

UO-22 was launched on 17 July 1991. It's now Non-Operational.
I predict here that UO-22 might be passed over just 100000 of
the orbit number using the latest TLE.

OSCAR 22 (UoSAT 5)
1 21575U 91050B   10212.53322685  .00000036  00000-0  25462-4 0  8963
2 21575 098.4959 161.9541 0006690 228.5705 131.4898 14.39726937999601

  100000 - 99960 = 40 ... orbit numbers until 100000
  40/14.39726937 = 2.778304619 ... orbits/mean motion = days
  212.53322685 + 2.778304619 = 215.311531469 ... epock time

  215 - 212 = 3                  ... 3rd Aug 2010
  0.311531469 * 24 = 7.476755256 ... 7 hours
  0.476755256 * 60 = 28.60531536 ... 28 minutes
  0.605315360 * 60 = 36.31892160 ... 36 seconds

Therefore it is 07:28:36 UTC, 3rd Aug 2010.

It maybe contains +/- one and a half hour's obserbational lag.
In addition, the counter number returns to 0 when the orbit number
exceeds 100000.
