19:45 Ready to open. Cart 2 plt 634 up the telescope. The mostly clear sky, but
humidity gorwed rapidly up to 84% at the sunset. 
20:50 telescope open, clear sky. we go to field and didn't find stars -probably
the rotator's amplifier hasn't been reset. We axis init twice and found a fk5
star. 

We also found the rotator error:

Seeing varied from 2.5 - 3.4" (strong wind NE).

After 5-th exposure we gived up with this plate and according to the 
SOS recomendation:
QUICKEXTRACT: sdR-b2-00010729.fit: WARNING: Large flexure flat<->science 
(Post-calibs recommended!)
we did postcalib as well.

PT reports seeing about 4 arc sec! But we are trying wtih a new cartridge:
9 plt 644.
