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. |

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. |

Telescope computer was in blue screen revealing that it had rebooted. I logged in, enabled alt-az motors, homed and parked the telescope. Restart of the monitor envoked a message saying that the CMOS controller was not running. The camera was then rebooted and the camera controler restarted. After that everything seems to work in the web control panel. |
