Summary
----------------------------------------------------------------------

=> No observations tonight. Major tracker failure was fixed, but
TCS has problem to communicate with SOMMI and telescope still
does not work.

=> Brilliant weather with 1.2-1.3" seeing.

=> We accidently press button "Scan Drift" and PDET software dies.
We tried to restart it, but have major fault:
SDSU HARDWARE FAILURE.

After that the temperature of the shutter solenoid starts to grow.
It was about 45, when the next restart of PDET goes correctly.
The temperature of the shutter solenoid starts to go down after that.
