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. |

The dome did not close correctly in the morning |

Dome |
Telescope and dome control system reported an error which after acknowledged the dome closed correctly. Next time Antonio on duty he could check the dome slit gear. Maybe it needs to be replaced? |

Observations did not start after sunset, and the weather is fine. |

Servers ? |
PROBLEM is gone/solved -- PERHAPS there were no objects available for the first ~30min ... seem ok now. Tried to abort or_req 93185 ... as that was in the queue, but only for execution after midnight. Other time critical ORs are inserted for after 22:00 UT, perhaps that is affecting something ? Comment fom Mads: The conductor had crashed eariler that day. |
