2018-03-14 Slit guider not working. Could not connect to camera Mads and Paloma Spectrograph The IAC night operator Paloma was contacted and went to the container after an hour. The USB was plugged wrongly into kvmtenerife and after a while she understood and plugged it back into sstenerife and it worked again. None Edit
2018-03-06 Sigu guide target of. Mads Spectrograph Changed guide target from 325 251 to 325 243 for slit 5. After 4 exposures of 24 Sex. Change only applied for that OR None Edit
2018-03-06 Leakage of pressure hose for telescope breaks Antonio, Pere and Mads Telescope Error arising on power on - pressure not reach - Antonio check and found a leakage on the blue pressure (air) hose going from the container to the telescope. The leakage was at the container exit. Fixed with gaffa tape and a clamp. Show Edit
2018-03-02 WXT520 weather unit was replaced with spare. The spare was sending garbage. Mads, Pere, Antonio, Roman and Eric weather station WXT520 was replaced. Cables mounted to screw terminal (20p) on print board at WXT520. Unit sending data but not reable. Eric changed baud rate on moxabox to 4800 and then it worked. None Edit
2018-02-26 Dome would not move in azimuth Mads and Adrian Dome The IAC night operator Adrian was called. He checked and saw the dome az gear was out of the rail. He pushed it back and it would move again. Show Edit
2018-02-19 WXT520 weather sensor broken Antonio, Pere Weather station The wxt520 fell of the pole during the ice period and the wind sensor seems broken and not reporting wind. No obvious damage on the unit. The unit was mounted back on top of the pole until weather permits for a replacement. Show Edit
2018-02-19 Fuse switching off Antonio, Pere Telescope Two fuses (012-1F1 and 012-3F5) in the control cabinet were switching off. These are connected to the power plugs at the telescope base. After unpluging and repluging the Ethernet switch in the nasmyth electronics box all was fine. Show Edit
2018-02-19 GPS replacement Antonio, Pere Telescope The GPS broke on the 17th of January. A new GPS from Astelco/Tau-tec was shipped to Tenerife and the receiver inside the control cabinet was replaced. Not the antenna. Grounding was added to the antenna. None Edit
2018-01-24 Antonio, Pere Spectrograph Unstacked the mounting (motorized rail) of the fibres at the PST Show Edit
2018-01-24 Check greasing of the rollers at the dome. Add some but was OK Antonio, Pere Dome None Edit
2018-01-23 PST cannot home motor 4 Frank Preslit table Homing of PST failed for motor 4 - beam selector. result of 'pst homeAll' attached Show Edit
2018-01-23 Replaced 5A fuse on the temperature controller Antonio Spectrograph Identified where fuse was (see picture), found a similar one elswhere and replaced Show Edit
2018-01-20 Target does not hit the slit-center (slit 6) Frank Spectrograph Changed sigu guide_target (yvalue from 253 to 245) None Edit
2018-01-20 Stopped the Conductor Frank Science operations of the telescope The conductor is stopped because blind pointing is not functional due to the broken GPS. None Edit
2018-01-20 Spectrograph heating unstable - see attached plot for the last 7 days Frank, Eric Spectrograph temperature control several restarts by Eric... but not fully stable... not sure what is wrong. Antonio found a blown fuse - probably due to the power failure(s) last week. Show Edit
2018-01-18 GPS is broken - several tests by Santiago and Michael, showed the unit to be broken. Frank, Pere, Santiago, Michael Ruder GPS A new unit is being configured by TauTec, can probably be sent around 20180123 and installed by observatory staff. None Edit
2018-01-16 2-3 power failures between 20180116 and 20180118 - caused all systems to stop Frank, Eric, Pere, Santiago All, recovery was slow - Manuals urgently need updating before next holiday season. Major problem with the slit guider, the computer would not detect it. MANY attempts of pluggin/unplugging did not work, until moving to another computer and then back..... Seems the USB drives for the solar experiment somehow did not allow the guide camera to be detected. .... a more robust process/method must be established. None Edit
2018-01-11 Re-installed Calibration Unit for BlueSpec Antonio, Pere, Nicholas None Re-installed Caibration Unit None Edit
2018-01-11 Reset switch webcams & adjut position Antonio, Pere None Reset switches for webcams in Cielo Nocturno & container. Adjusted position of the container webcam to better see display of Cells PS None Edit
2018-01-04 None of the SONG webpages worked during the day Frank Webserver 'destroyed' srf on sscentral, and restarted it. This worked. None Edit
2018-01-01 Monitor did not prevent observations on 2017-12-31 (as expected). Frank Computers/Monitor All looked in good order - but since there is no staff the telescope was stopped (OR = 27470), closed and shutdown. The monitor will be re-started on 2018-01-02, after noon. None Edit
2017-12-26 Reboot of the slit guider after failure reported by Mads on 2017-12-23 Frak, Santiago Slit guider Santiago disconnected and then re-connected the USB3 cable and power cable for the slit guider. After this things worked as normal during the night. None Edit
2017-12-23 Slit guider problem... gets stuck on sstenerife... Mads Guiders The slit guider daemon running on sstenerife was hanging. None Edit
2017-12-21 Conductor crashed early in the night Mads All Restarted the conductor on song.sscentral.prv. It had crashed because the database had problems None Edit
2017-12-17 Dome offset Mads Dome The dome was off by too much and vignetted half of the pupil. The controller was power cycled. None Edit
2017-12-17 Not observing from 1 to 5 UTC. Mads Telescope The wind was above 10 m/s from east and the telescope would not open up into the wind. None Edit
2017-11-30 Power failures on site Mads Telescope 2 short power failures happened during night. Those made the tcs software hang and the monitor could not connect. An panic-message about running on UPS was not cleared. Doing it through AsTelOS worked. None Edit
2017-11-15 Calibrations lamps were on while observing Mads Spectrograph Updates to the obsering scripts left the calibration lamps turned on for a few of the first spectres this night. Might cause scatterd lidt in science frames. None Edit

2017-09-25 Stellas dust sensor stopped working Frank Dust-sensor Stopped the dust sensor as the weather looks non-dusty. None Edit
2017-09-14 At around 6 UTC in the morning of the 15th the wire for the lower hatch of the dome broke and the dome lower hatch could not close. Mads Dome Called the OT night operator who confirmed the broken wire. There were a thunderstorm meanwhile. The OT maintenance team would find a wire to replace the broken one. Show Edit
2017-09-13 Telescope could not clear errors --- emergency buttons pressed.. Frank Telescope and dome took screenshot (attached). Cleared errors after a while... stopped monitor, closed dome with astelos. started monitor. thinks seem to start again. Show Edit
2017-09-12 The telescope offsets were above 500 arcseconds in both directions and telescope focus above 5. Seems the guider had gone wild Mads Guiders Set az, zd offsets to zero and the focus to 2.7. None Edit
2017-09-12 Problem with guiders seems to be a setting in the TSI "problem" Mads Telescope This can be fixed.... None Edit
2017-09-12 The slit guided continued to run off. Maybe a piezo controller problem. Mads Guiders Stopped the slit guider None Edit
2017-09-09 Dome was highly offset in the following morning at shutdown. Reporting aligned with telescope Mads Dome Medium high wind this night. Power cycled dome controller Show Edit
2017-09-07 At 20:30 utc the dome was rotating endlessly Mads Dome Power cycled the dome controller None Edit
2017-09-06 At around 4 UTC the TSI reportet power errors with the telescope which could not be cleared Mads Telescope The error said "DC voltage too high" and "I2t power too large". I managed to close the dome and power off and left it like that. An effect of the OT maintenance work on the power line yesterday? None Edit
