09:20 UT: End of the night

* Towards the end of the night there were some instrumental problems with SOFI - the software did not read the right exposure time from the OB's, and it was increased by around a factor of 2. We also lost some observation time due to a problem with the count down, which for some reason did not stop at 0:00 and went into negative values of almost 3 minutes. We hope that these problems did not affect the images.
