The observations below were made during my winterholiday in Austria.
I stayed in the little village of Weissbichl (county Pflach) near the town of Reutte im 
Tirol; obs-site: 47.5153 N, 10.7083 E, +850 m.

Weissbilch is situated in a broad valley near the river Lech. Just outside the village I 
had a superb dark obs site. The surrounding mountains came to about 20 degrees 
elevation.
In the morning comet Hale-Bopp rose above the mountainrange in the east. Quite a sight 
as in about 15 minutes the tail first rose over the mountainrim until within a minute 
the comet appeared. It looked like a car with a big headlight slowly drove up to the 
rim.

Finally saw TiPS again. The tether was S, mag 7. The endsats were flashing Irr,
with Ralph as bright as mag 4 and North to mag 5.

It seems like the period is going up slightly. Second obs on Feb 03 shows synodic 
effect.


Saw these 'unknown' sats during the observations above.
Running Skymap and a 5000 TLE-file back home gave some candidates.
 
97-999 A 97-02-03 03:49      LB                       slowly var, mag 5->6
Moved from RA=17h40 d=+57 to RA=15h20 d=+32
Only #17129 86- 19 Y on the right track; to be checked again

97-999 B 97-02-03 18:11:09   LB   19.2 0.2  10  1.92  AA, mag 5->inv
Moved from RA=0h d=+85 to RA=2h d=+65
#12201 78- 26 AS and #02180 66- 41 B are both on the same general track. Need to make 
more observations to make a positive ID.

97-999 C 97-02-04 04:45:03   LB   60.1 0.5  16  3.76  AA, mag 5->7
Moved from RA=20h50 d=+62 to RA=21h40 d=+47
No suitable candidate showed up. Perhaps someone with a bigger TLE-file will give it a 
try? I only have a Allsat.dat with 8000 TLE's from 1996 July.


Back home in Alkmaar the weather is clouded and rainy; also the forecast isn't good.
Will have to watch the Hubble-service mission on CNN to see some satellites.
