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.

IRAS made an almost overhead pass and was steady.

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.
