Observations stopped due to serious telescope error |
Frank Grundahl |
Telescope |
Checked monitor.log and saw an error message about the az. Drives. Started Astelos, to see the error there, but decided it was above my level so did not perform any telescope actions. Closed the sideports and went back to bed, since the mirror covers and dome were already closed. - comments by Mads: After a complete system reboot of the telescope control system the telescope was again operational. |

1. changed status to abort for two time-critical obs. inserted for lam Ser. - did not help ---- Could not see any error messages in the log files. Tried to stop/start or_scheduler, and then monitor ... did not work. Then stop monitor and close mirror-cover, flap and dome with Astelos. Power is still on. It is probably something simple.... but I cannot figure it out :-) ... Comment from Mads: The conductor had crashed in Aarhus |

Slony was not replicating observing requests to Tenerife because of the ongoing slony work... stopped slony on central, removed triggers for song-mtkent, song-central, song-tenerife and re-added for song-tenerife and restarted slony which made it replicate to tenerife again. |

Mads, Pere and Antonio |
Spectrograph |
Antonio and Pere opened the spectrograph and inspected the motor. Mads moved it remotely and when this was possible it was fixed at location 6 until a major operation to inspect, find cause and fix is planned and possilbe. |

Tried checking the code to see if the issue was there. Then tried slowly to move the motor after reset of error state. Did not work. Then power cycle. Did not work -> out of operation |

Saving spectre to disk is slow.... takes about 13-15 seconds in the SaveAsFITS function of the Andor SDK |
Mads |
Servers |
This started occurring after the power failure on the 12th of december where the save to disk time increased by 2 seconds. On the 20th of december the save to disk time increased to 13-15 seconds. Only an issue in the SaveAsFITS function... strange.\n\rFor now a temporary solution is to read out the raw data and create data structure manually. This reduced time save to disk time to 2 seconds. |

Stopped the observations and waited until calibrations had finished and then started the observations. Investigations (remote) needs to be performed to figure out the issue. |
