Hi everybody,

Just observed the decaying Cosmos 1278 satellite (Sept. 01, 01:43 UT) :
It took me by surprise because it was about 1.25 min early using Alan's
predicted elset :
Cosmos 1278                                      2215 x 99 km
1 12547U 81058A   00245.04249860  .75446567  13972+0  19506-2 0 92737
2 12547  62.8625 151.5443 1403881 195.6359 159.5448 13.27398960142311

I was checking the time on my watch, then came back to my 20x80 and
saw the sat had already crossed my reference stars. I followed it until
shadow entry and noticed it was in a relatively slow tumble with a period
of about 9 seconds and a minimum mag of 5 and max of 3. The increase
and decrease in magnitude were smooth. It was a 63 degree elevation pass.

Cheers,

Dan
