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. |

None, after the target was acquired. |

The issue was that the conductor could not connect to the database where observing info is located. The issue resolved it self at 04:40. |

The following error messages were sent out: "The monitor daemon is hanging somewhere and a restart is most likely needed. Please check if things looks fine!” and "Slony is not replicating data from tenerife to central!!!” When trying to access the webcams and SODA page, i found both offline. After about 15min both came live again and the problem seems to have dissapeared. |

After coming home for dinner, no one on watch, so took it. Monitor was not running, so started it .... after ~10min things started, but monitor stopped itself, tried to restart, but it stopped again. The 'client_abort_acq' did not work, so stopped or_scheduler. Then tried to close the hatch and dome ... the hatch closed, but when the upper hatch closed I could see the lower hatch was not closed properly, despite Astelos reporting it closed ... so opened the uper/lower hatces agin... then the telescope slewed to a new objece (despite the monitor was not running!): ... then I closed the lower and uppper hatch, parked the telescope ... during which the 'both-limits-active' ocurred.. and then the telescope powered off.... Not sure what all the reasons for this are, but guessing perhaps the new(?) monitor. |
