MADS: For AFTER the vacation ! :-) Ghost in the machine ???? Yesterday I stopped both T1 and T2 monitors and or-scheduler --- yet, I discovered in the afternoon that the telescopes had opened and tried to observe, however acquisition always seemed to fail. In addition at the end of the night, when the sun was 3.5deg below the horizon both domes were still open!! |

I Closed the domes manually from HW. One observation + many ThAr was obtained in the night. NO flux on the ThArs. |

It seems that I cannot home/move T1, T2 using the PWI2 interface. Tried to restart PWI on T1 ... seemingly no effect. I have disabled T1, T2 monitors and the OR_scheduler and closed the domes. |

Reoccurring issue with calibration light motor slide preventing observations |
Mads, Pere and Antonio |

The motor rails and bearings were checked and adjusted by Antonio but it continued to fail after few movements. I have decided to stay closed until Antonio and Hector will try to change the rail to a new one on Monday the 4th of August. |

Mads |
Telescope 2 |
Re-enabled the motor and then moved the telescope a bit. This raised another error (motor pulse too high). I then power cycled the PW control box. Re-started PWI2, connected and enabled and then the homing went well. |

From the daily light on slit checks it was noticed that light with iodine was not centered on slit |
Mads, Duncan, Frank, Jonatan |
Spectrograph |
The spectrograph box was opened and the Iodine cell was rotated until spots were aligned on slit. Afterwards it was noticed that this was most likely not needed and the confusing was originating from misconfiguration for the daily check images. |

Telescope computer was in blue screen revealing that it had rebooted. I logged in, enabled alt-az motors, homed and parked the telescope. Restart of the monitor envoked a message saying that the CMOS controller was not running. The camera was then rebooted and the camera controler restarted.
