Cannot get Focuser to connect on SONG telescope 2 |
Mads |
Telescope 2 |
Have tried to stop/start PWI2, power cycle PW box in dome etc but PWI2 just reports: - Controller not found on COM1. Check Power and Cables - |

SONG telescope 1 oscillates back and forth in azimuth when trying to initiate it and after moving it a bit. |

I have tried to power cycle the Plane Wave control box a number of times. Home the telescope a number of times and stop start PWI2. |

SONG Telescope 1: - Azm Error 29586 Fedback level too low - the telescope cannot move in Azimuth |
Mads |
Telescope 1 |
Power cycled the PW box and restarted PWI2 and rebooted the Tel-com. The error continued to be there. Maybe something is wet in the dome? |

No connection to anything in the FUT dome so either power or network connection to the dome is lost, likely due to bad weather. Thus, the "Urgent" level refers to urgent when weather allows observations again. |

Connection to guide camera on SONG telescope two is lost. It has been getting worse and worse in providing good images and finally today the connection is totally lost. |
Mads |
T2 guider |
If the on-site team could check the power and network connectors from the camera two the PDU and switch in the dome it would be a great start. Meanwhile the telescope is not usable. If the camera is broken we have a new guider in Aarhus. |

The flux level of SONG T1 is very low. |
Mads |
Telescope 1 |
It looks like it must be somewhere inside or before the nasmyth guiding unit since not much light hits the guide camera either. Maybe some bug are infesting the guide unit? or something else in the telescope is reducing the amount of light significantly. |

The boltwood weather data periodically (every few to five minutes) reports values that incorrectly suggest rain. Since you are going out to Mt. Kent, could you please check up on that? Thanks |

Cannot connect to telescope in PWI4. Get Error: "2025-10-28 02:15:52.195: ERROR System.Exception: Unable to connect to Azimuth/RA axis: The operation has timed out. at PWI4.MotionControllers.ElmoMotionController.Connect()". This seems similar to earlier error when the power to the motor was somehow disconnected. Please investigate. |

Check all motor combinations and figured out that the Iodine cell position has changed....? The new position is now added to the code and all should run correctly. |

No power in the FUT dome since 03.50 . Likely breaker switch, since SONG teleskopes also lost power, but that is back |

The SONG telescope 2 reports -Azm Error 29956 Motor pulse usage too high- and will disable motors after short movement. |
Mads |
Telescope 2 |
I have tried to power cycle the telescope control box and restart PWI 2 and the PC. It seems it is and actual issue with the telescope azimuth movement. Not sure if it needs greasing or something else to ease the movement? |

Duncan and Frank adjusted the spectrograph |
Frank |
Spectrograph |
No ThAr light: The controller did not deliver a sufficiently high voltage - We switched to the old, non-adjustable power supply. This worked! We adjusted the iodine mirror such that the fiber outputs fall exactly on the ThAr fiber output. All modes (flat, flati2, fp and ThAr) seem to work right now and give light on the detector. |

No connection to IRF90 (rotator and focuser). Are power and connections to the unit OK? The values reported for the focus position have been acting strangely for days prior to this. |

MADS: For AFTER the vacation ! :-) Ghost in the machine ???? Yesterday I stopped both T1 and T2 monitors and or-scheduler --- yet, I discovered in the afternoon that the telescopes had opened and tried to observe, however acquisition always seemed to fail. In addition at the end of the night, when the sun was 3.5deg below the horizon both domes were still open!! |
Frank |
Telescope |
I Closed the domes manually from HW. One observation + many ThAr was obtained in the night. NO flux on the ThArs. |

MADS: I put urgent, but guess you are on vacation, so this is for after :-) :The weather is great and not errors reported anywhere - but no observations. |
Frank |
Telescope |
It seems that I cannot home/move T1, T2 using the PWI2 interface. Tried to restart PWI on T1 ... seemingly no effect. I have disabled T1, T2 monitors and the OR_scheduler and closed the domes. |

No calibration light through fibres for quite some time |
Mads |
calibration shutters |
Checked if light from ThAr and Flat came to guide unit in nasmyth which it did not - most likely the shutters in the guide unit are not activated in remote mode. @Duncan: could you please check and activate them next time at MtKent? |

Cannot connect to telescope and telescope in strange position. When trying to connect through PWI4 one gets an error: Axis0 communication channel not found. Is the device plugged in and turned on? See attachment. Duncan, feel free to call me at 91959459 at any time if you need help troubleshooting or to test something. |

T2 did not home and errors where shown in PWI2 - Tracking error |
Mads |
Telescope 2 |
Re-enabled the motor and then moved the telescope a bit. This raised another error (motor pulse too high). I then power cycled the PW control box. Re-started PWI2, connected and enabled and then the homing went well. |

Calibration light from fibre in SONG T1 was not centered on science fibre. |

The fibre outout from the calibration fibre was adjusted using the alignment screws. The alignment is not perfect but much better now. |

From the daily light on slit checks it was noticed that light with iodine was not centered on slit |
Mads, Duncan, Frank, Jonatan |
Spectrograph |
The spectrograph box was opened and the Iodine cell was rotated until spots were aligned on slit. Afterwards it was noticed that this was most likely not needed and the confusing was originating from misconfiguration for the daily check images. |

The calibration fibre for SONG telescope 1 is misaligned with the science fibre. See attachment |
Mads |
Calibration unit |
Light from calibration unit was checked on the guide unit in the nasmtyh of T1. Afterwards light was send back through the science fibre to determine the location on the guider. These two do not align and the calibration fibre should be adjusted on site to hit the science fibre better. |

Added it to the task as time worthy, since the wavelength solution on Mt. Kent is stable and people are on holiday. But it needs be looked at somepoint during August at the latest |
