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.

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. 

23:20 cart 9 plt 644: gotoField bring us stars into the fibers at once.


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

00:10 SOS reports S/N  around 1 - the current seeing variable: 3.0" - 4.4"
Very bad S/N for this cartridge. 

01:42 Next cartidge 6 plt 656 on the telescope.

02:48 We lost the exposure due to the hardware fiducial reading problem 
(axies were halted):
Aug 27 02:43:08 sdssmcp    tLatch     dsc_I_trcInfo az fiducial 15.69 deg 
Aug 27 02:43:08 sdssmcp    tLatch     dsc_I_trcInfo      err = -3850915   
poserr = -3850958 ticks 

first time occured on:
Aug 27 01:56:54 sdssmcp    tLatch     dsc_E_trcErr Invalid barcode in azimuth:
 fididx = 12288, pos = 1096683686 
Aug 27 02:01:55 sdssmcp    tLatch     dsc_I_trcInfo rot fiducial 35 (204.52)
 deg 

We didn't refiducilized the telescope in  azimuth axis, since the telescope
was still tracking and we've been collecting data. Seeing had dropped below 
3.3 (usulay 2.7)
03:40 Seeing has dropped below 2.5" - we are getting usefull data finaly! :)
(the efficiency over 60%).
Yes - we finished this plate! after sixth exposure (5-th - one lost due to the 
hardware problem).

04:20 cart 3 plt 666 on the telescope - observing.
