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. |

A problem with slony ment no observing requests were send to Tenerife. A restart of the database in Tenerife and restarting slony made it replicate again |

A bug in the software that handles the side ports when weather turns good from bad made the code fail. This is now corrected. |

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. |

Power failure - Circuit breaker flips (labeled UPS in). See attached image. |
Mads, Rosa (support ast) |
All |
Power failure happened while I was checking for light through the whole system; dome open, telescope tracking. When Rosa flipped power on it started powering on things but after a while it flipped again. A propper check of the electrical system is needed. Something is not well on the power grid. |

Very few observations during the night - despite good weather - No errors reported. It seems that only one target was observed, with flux. |
Frank Grundahl |
All ?? |
None - I am wondering whether this is a pointing model problem,but do not know. There was flux on the guider for one target, so probably not the guider ? |

Looking at the slit-guider image, betaAql was way off the slit and appears de-focused. Watching for several minutes the image seem to update, but without any pointing or focus corrections. |
Frank Grundahl |
Slit-guider |
Tried to just change focus in Astelos (-0.1mm) ... this made the guide image appear very sharply focused. Applied manually offsets in Astelos to move the star to the correct guide spots. This put light to the slit, but still no active guiding. Then tried to stop/start the slit-guider from 10.8.0.80, but seemingly this had no effect, and there was no output to the log file. Not quite sure what the problem is. |

No observations from around 3 UTC caused by no new ORs send to site |
Mads |
Servers |
A database machine (db_backup) in Aarhus was hanging and causing problems for the main user access database (db_aadc on trinity). This made the Conductor not able to fetch new information for sending ORs. After reboot of the db_backup machine it seems to run fine again. |

During the observation of beta Aql the connection to the telecope (Astelco) was lost (around 2 UTC). However, I was asleep so the problem has stewed until 6 UTC. Attempted in the morning to activate shotdown but did not work. |

Aquistion gone 'rampage' --- two first targets ok - then a lot of inserts of HD185144 ... apparently not acquired, although it was just observed ... I saw it on the guider... then keeps inserting more ORs of HD185144.... |

Tried to 'change_or_status' for the extra ORs .... not effect - the system still thinks that 185144 should be observed, but cannot find it .... |

At the start of the night the acquisition of the first target (HD109358) failed ~10 times, resulting in many inserted ORs. There seem to be a problem with the pointing model or focus guess. |
Frank Grundahl |

None, after the target was acquired. |
