2026-08-24 The dome cannot be referenced in the rotation/azimuth direction Mads Dome Tried to move it past the reference point around 60 degrees N but nothing happened. The sensor needs to have on-site maintenance. None Edit Tenerife 294
2026-08-14 Offsets from acquisition was getting too large Mads Telescope Made a new pointing model None Edit Tenerife
2026-08-14 The dome flap reported not closed even though it was Mads Dome Power off the telescope and on again. Opened dome slit and dome flap and was then able to get it properly closed and sensors reported closed. It would be great if Antonio could inspect the sensor for the dome flap. It might need some maintenance. None Edit Tenerife 292
2026-08-14 Warning on telescope altitude motor controller over temperature occurring often Mads Telescope This is just a warning but happening often. Maybe Antonio could investigate. I am not sure where the motor controller for the telescope altitude/zd motion is located. None Edit Tenerife 293
2026-07-29 The cloud sensor seems to have changed it sensitivity so the sensor reported clouds even though there were not -- but dusty Mads Cloud sensor Changed the limits in software for when the sensor reports cloudy. Maybe a cleaning of the sensor by the local team will help? None Edit Tenerife
2026-03-28 Could not find any stars Mads Telescope After power came back at OT I restarted everything. No stars were found and had to do a new pointing model. Did with 40 stars and RMS of 2 arcseconds. None Edit Tenerife
2026-03-12 The telescope is not observing any star (last observations was yesterday). On the webpage it looks like the connection to the monitor was last checked 12:07:58. Jonatan Rudrasingam Software (Monitor) Activated shutdown until problem is fixed. None Edit Tenerife 288
2026-03-11 No observations since 23:30 UTC Mads PST Motor for calibration mirror slide is stuck. Might be due to bearings bar comming loose of the rail as with the old one. Show Edit Tenerife 287
2026-03-06 Vaisala weather station unit not working Mads, Pere, Antonio Primary weather station unit Antonio tried many things and got the unit to send some info but no weather values only internal house keeping data. Conclusion is that it is broken Show Edit Tenerife 286
2026-01-22 Errors from the telescope control system in relation to the hexapod is popping up all the time at startup and preventing observations Mads Telescope Clearing will not make it go away in most cases. I have now tried to make the telescope NOT power off and on but in stead keeps powered on and will park back at 75 degrees in altitude to relax more on the hexapod. Show Edit Tenerife
2026-01-15 Errors for M2, Active M2 ... errors when starting up .... (the monitor was not running, so I started it). Frank Telescope Tried numerous times to clear the error in Astelos during telescope startup, but without success. None Edit Tenerife 279
2025-11-26 Replaced circuit breaker for SONG UPS input line Miguel (MOT), Pere None A less sensitive circuit breaker installed None Edit Tenerife
2025-11-25 Circuit breaker for the main inpout line to UPS went OFF (down). Slit open !!! Pere, Borja (Operator) Dome Borja (guided by Antonio and Pere at phone) took care to close it properly and breaker ON again None Edit Tenerife 277
2025-10-30 No light from stars at all Mads Telescope I was not able to find any stars at all. Not even the moon. Possible to see scattered light in slit guider with light on in the dome but nothing from the sky. Closed down and more testing tomorrow to investigate. None Edit Tenerife 274
2025-10-27 General check of the dome elements (shuter,flaps,cables, rollers, azimuthal movement etc) plus telescope cables. OK zntonio P, Pere Dome and telescope general check all of mdchanisms Show Edit Tenerife
2025-10-25 Software error reported. No observations Pere,Mads telescpoe The telescope control software is reporting some kind of error with homing of the hexapod None Edit Tenerife
2025-10-21 No observations after weather improved Mads Telescope Telescope control software was not working correctly. A restart solved it. None Edit Tenerife
2025-09-18 No observations during night Mads Telescope For some reason the telescope was powered on at the time where it should be started up by the software. Since this is seen as an overwrite safety prevented observations. None Edit Tenerife
2025-09-06 An error occurred during the closing of the dome flap ("the while loop time-out so the dome flat might still be open"). Jonatan Rudrasingam Servers (I think) Activated shutdown seem to have closed the dome, although not sure if it would have closed without activating it. None Edit Tenerife
2025-08-28 Dust level was always only just below yellow limit Mads Weather station I added and offset to lower the value based on visual inspection on the web camera None Edit Tenerife
2025-08-04 Replaced the mechanisms (rollers,etc) of the PST Antonio P., Hector (MI), Pere Spectrograph Installed the mechanisms we bought in advance. Need to check remotely and see how it works None Edit Tenerife
2025-07-29 Reoccurring issue with calibration light motor slide preventing observations Mads, Pere and Antonio Pre Slit Table The motor rails and bearings were checked and adjusted by Antonio but it continued to fail after few movements. I have decided to stay closed until Antonio and Hector will try to change the rail to a new one on Monday the 4th of August. None Edit Tenerife 267
2025-07-27 No observations during night Mads Pre slit table - calibration mirror slide The same problem as a week ago with the motor slide on the pre slit table. It reports issues and cannot be moved by software. On-site manual assistance needed. None Edit Tenerife 265
2025-07-25 The telescope will not properply shut down around ~11 am local time. While the mirror covers and dome flap are closed, the dome slit remains open. The SONG mail keeps spamming that the dome was not properply closed Jonatan Rudrasingam Dome Activated shutdown and added it to task None Edit Tenerife 264
2025-06-09 An error occurred during the closing of the dome flap ("the while loop time-out so the dome flat might still be open"). Jonatan Rudrasingam Servers (I think) Activated shutdown seem to have closed the dome, although not sure if it would have closed without activating it. None Edit Tenerife
