I send this message early this morning, but it probably didn't get through.
I apologize if it's send to you twice.
Observations January 17.
A clear sky with now and then some thin clouds.
The observation times are in minutes. I had to use my old mechanical
stopwatch, as the battery of the usual stopwatch was empty. Then you know
how
used you get to a stopwatch with more laptimes. This one has none!

This is 67-01 X (06779) the mis-identified by NORAD Intelsat 4-3 rk
The last time I observed it was in 1997 and it was slowly going up at almost
9 sec. To be watched again. Some flashes were almost inv. Height was more
then 11.000 km.

UME 2 was flashing nicely. Once you got it in view it is easy to follow.

Iridium 27 (24947) showed irregular fainter flashes in between the distinct
brighter flashes I measured. The period is in good agreement with the one
measured by Jim Nix in his message Jan 16.
Greetings and clear skies
