a) Transverse data taking was started on August 2 13:00 with polarizations 
-83.2 %, +81.9 % and -75.0 %. On Monday August 6 back to longitudinal 2.5 T 
field with polarizations -81.3 %, +80.1 % and -71.9 %. Restart polarization.
Tuesday at 12:00 first field rotation from +650 A to -650 A. PLC CPU failure 
at 15:15, only the vacuum diffusion pump affected. On Wednesday attempt to 
replace the CPU with new unit, but unfortunately the old memory card is not
compatible with the new CPU. On Thursday polarizations -95.2 %, +88.6 % and 
-85.7 %, start frozen spin mode and 17:30 go to -260 A solenoid current 
(1.0 T). On Friday 11:00 first field rotation in 1.0 T field. 

b) Jaakko: using the the May 2 TE-calibration the polarization loss rate in
0.63 T transverse field 0.27 - 0.35 %/d upstream, 0.21 - 0.58 %/d middle
and 0.47 - 0.61 %/d downstream in different periods.

c) Miroslav reported on Spin Prague 2007. Norihiro reported on the 
Circum-Pan-Pacific Symposium on High Energy Spin Physics held in Vancouver. 

d) Fabrice was calculating magnetic field close to Recoil-Proton-Detector 
(RPD).
