No observations during night |
Mads, Pere |
Pre slit table |
The calibration mirror slide including ThAr fibre feeder, solar fibre feed etc is not working. It needs on-site inspection of the pre-slit-table and specifically the specific motor slide. |

Testing of pointing |
Mads |
Telescope |
I believe I found the cause for the bad pointing on specific targets. A missing division by cosine to the declination when calculating the ra proper motion seems to have solved the issue. fingers crossed. |

Telescope and dome control system seems to not be able to read the dome azimuth motor value |
Mads, Pere |
Dome |
Tried to power cycle dome controller, reboot full telescope server system etc but nothing seems to make the dome work... Manual inspection on site needed. |

Tested whether we can hit the slit properly again by changing the ThAr-fiber illumination mirror position - YES we can. |
Frank |
Spectrograph |
The new encoder position for ThAr and motor 4 is 1930000 (was 1790000). Figure attached to show the new position. |

This night, and yesterday, there seemed to be lots of problems in the early night to find objects -- perhaps a problem with the PM ? |

Problem with the FITS headers of the RAW files: the slit is listed as -1 and the Camfocus as 1 .... This makes songpipe crash -- something must be wrong with the camera software. |

An error ocurres when the telescope is shutting down "The Error message was: [CONN-ID: 87271] "DRIVES|2:DOME[0]|2;DOME[1]|2;DOME[2]|2:ERR_DeviceError|timeout reading status|2|DOME[0];ERR_DeviceError|timeout reading status|2|DOME[1];ERR_DeviceError|timeout reading status|2|DOME[2],SYSTEM|7:CABINET|7:ERR_PhaseWatcher|Wrong 3-phase seq./undervoltage|5|CABINET;ERR_UPS|Power failure. system running on UPS battery|1|CABINET;ERR_DeviceError|timeout reading status|2|CABINET,AUXILIARY|0::,UNKNOWN|0::"" . This message is repeated and sen via email to the watchmen (Dennis Stello noticed that he received lots of email pr. minute. Neither me or Stello are watchman for tonight). Looking at the observer page the dome state is still open, this is problematic, since the humidity is high. I tried to activate the shutdown, but it didn't help. |

Telescope was shut down during the night using 'Total Shutdown', but in the morning at 08:14 dk time the mirror covers and dome where completely open and pointing at low altitude to the east. |

Previously, I activated the shutdown for the telescope because connection to software and I couldn't acces the observer page. Now the observer page is backup and I can see that the telescope has not shutdown. Since morning is approaching someone needs to shutdown the telescope as soon as possible. |

The slit motor is stuck and needs on-site manual actions. Actions needed by Antonio: The spectrograph box needs to be opened and the motor should me manually moved and the spindle greased. |

There seem to be a problem with the referencing of M2 - there are entries in the monitor log, and they can be seen in Astelos.This problem may possibly have been there the last few days causing no observations. |

I tried to acknowledge the errors, and then things began the startup process, but the error returned. Then wrote this report. |

IThe monitor hangs after errors in Astelco that cannot be cleared. This is possibly due to a bad switch, as reported by Pere on Saturday ... I have labeled the importance level to 'Important' since Mads is also contacted via mail.... :-) |

Checked that the dome and mirror covers are closed. The dome is not in the correct parking position, but that is acceptable. |
