2018-09-11 Stars hitting the edge of the slit Mads Spectrograph Applied automatic detection of slit offsets every day and activated the use of these offsets to adjust the sigu guide target for each slit based on the offsets determined in the evening calibrations. None Edit
2018-09-06 I changed today Thorim-Argon light bulb Antonio P. Spectrograph changed Thorim-Argon light bulb None Edit
2018-08-20 Pixel scale for slit guider was not correct Mads Spectrograph Measured the pixel scale from multiple targets and determined a new value. Going from 0.117"/pixel to 0.104"/pixel. Might help near zenith None Edit
2018-08-15 Morning checks failed Mads None Reference frames for ThAr was updated to new ones (20180704). This shows up as large displacement in x,y offsets (going back to zero). None Edit
2018-08-10 Dome and gears are revised Antonio P. Dome Dome. put fat None Edit
2018-08-03 Removed Solar-SONG FO assemby to be repaired at IAC Felix, Ezequiel, Kun and Pere Spectrograph removed the whole FO assembly as NO LIGHT at all transmitted !!! Show Edit
2018-08-02 Reparied and fixed the lekage of the compressor Antonio P. (container), Pere (remote) Telescope The decanter valve does not work properly, so there was leakage in the drain pipe. Antonio did not fix the valve but he made a stopper (at the end of the blue tube) to avoid air leaks... It seems to work properly now and pressure stable Show Edit
2018-07-29 Compressor failure - air pressure not reached Mads Telescope ... not fixed yet None Edit
2018-06-30 Temperatures were not read from the temperature monitor box Mads Temperature monitor box Powered off the box (pdu outlet 21) waited a while, powered on again and restarted the software (i2_write2db_daemon.py) None Edit
2018-06-25 Pupil guider not responding from 03 UTC stopping observations Mads Guiders From sunset an attempt to create a new pointing model which would work above 80 degrees in altitude was performed... with no success. The new PM was better in the other areas though. For some reason the pupil guider was not reacting to commands after 02:05 UTC. At 3 when the ongoing observations would finish and a -stop- command was send to the pupil guider it did not respond and made the observations stuck. A restart of pupu made it work again for solar observations to start in the morning. None Edit
2018-06-10 Series of events Mads Telescope, Dome and SkyCam-1 SMS was send at 22 UTC. Monitor was hanging. The problem was not obvious in the night but the telescope got back to observing. The problem was high wind making the telescope point away but the dome did not follow. After a while were no stars were detected on SkyCam-1 the light was turned on to save an image of the telescope/dome position. This made the SkyCam-1 saturate and stop taking pictures the rest of the night. Every half hour the dome controller was then power cycled the rest of the night. None Edit
2018-05-20 connect the fast camera PC with the power suply new. Antonio P Telescope PC fastCam Show Edit
2018-05-16 Side ports were not used Mads SidePorts Re-activated the use of the side ports to run automatically again None Edit
2018-05-03 The SENSOR OF CLOUDS ... when disassembling the cable had rust, possible cause of the fault, the sensor was put as seen in the photo, another sensor was installed in "test" with the same cable at low height (container ceiling) . Antonio P. /Miguel (MOT) Show Edit
2018-05-02 put nipple in the cut of the air hose that goes up to the telescope Antonio P. Telescope Show Edit
2018-05-02 Changed the gear that moves the dome for a new one manufactured in IAC workshop Antonio P. / Rafael (MOT) Dome Show Edit
2018-04-26 Startup of telescope failed due to: [CONN-ID: 4338] "DRIVES|0::,SYSTEM|2:CABINET|2:ERR_DeviceError|Air pressure lost|2|CABINET,AUXILIARY|0::,UNKNOWN|0::" Frank Telescope Cleared error manually in Astelos - stop/start monitor ... after this things seemed to be of... and obs. started again. None Edit
2018-04-26 STELLAs dust sensor stopped working at 1 utc Mads None Disabled the dust sensor in the standard way at 4 utc None Edit
2018-04-25 At the beginning of the night no ORs were inserted. The song.sscentral.prv virtual machine was hanging meaning the conductor did not run. Mads and Frank Servers From sscentral as root the virtual machine was rebooted using "virsh destroy song" followed by "virsh start song". After that the conductor was started again using "conductor -s" None Edit
2018-04-24 Dome was drifting off in the high wind (only in software the dome did not move physically) Mads Dome Powered on and move the telescope past the reference point which realigned correctly. None Edit
2018-04-19 washing of primary and tertiary mirror Julio M.I./ Antonio P. Telescope Mirror Show Edit
2018-04-15 Conductor problem Mads None The conductor was failing after rv-standard stars were not correctly setup in SODA. A known bug is present when changing rv-standard stars in SODA from the web page. None Edit
2018-04-13 Slit guider on sstenerife hanging from 1:30 UTC Mads Spectrograph Restarted the slit guider did not seem to cure the problem. Contacted the night operator to go and power cycle it by unplugging and plugging it back in. None Edit
2018-04-12 Dome flap open-closing procedure changed Mads Dome Changed to open the dome flap whenever the wind is below 10 m/s and it will stay open regardless of the telescope altitude. It should then close again if wind gets above 10 m/s None Edit
2018-04-12 Solar shutter active during night Mads Spectrograph The solar shutter was not deactivated after solar observing run. Lucky the weather was bad and we did not observe this night. The shutter electronics are connected to the big container PDU in outlet 13. Off means STELLAR shutter is active, ON means SOLAR shutter is active. None Edit
2018-04-10 Dome a bit offset Mads Dome Move the dome past the reference point (around 60 degrees north) and it was back aligned with the telescope None Edit
2018-03-31 sigu guide_target for slit 6 was a bit offset. Mads Guiders The star was hitting the bottom of the slit 6 edge and the y-coordinate was changed from 250 to 253. x stayed at 325. The change was applied at the end of the last MuHer run just before clouds were covering the sky. None Edit
2018-03-27 Cloudy and windy Mads Telescope and dome Closed down since it was comletely cloudy and wind around 10 m/s. Cloudsensor reporting "partly cloudy" and observations were tried by the robot. None Edit
2018-03-24 Scratch was running low on disk space Mads Servers Deleted star_spec, extracted data, skycam1 and 2 images to free 2.6 TB None Edit
2018-03-23 Pupil circling Mads Coude Adjusted M5 a bit to minimize the misalignment and centered the cross-hair in pugu to match the real position None Edit
2018-03-23 Solar shutter should run in stead of Stellar shutter when observing the sun for oscillations Mads and Ezequiel Spectrograph New electronics for the two shutters was installed and are now in operation. Show Edit
2018-03-23 Pointing model was bad Mads Telescope Made a new model using around 80 faint stars. The final model had an RMS of only 0.86 arcseconds. The best we ever had. None Edit
2018-03-22 The spectral orders have shifted on the CCD after the cooling pipes were remounted Jens and Frank Spectrograph The shift was roughly 20 pixels in the cross-order direction. This causes the orders on the CCD to shift by one - now the extracted spectra have one extra order in the blue, and one less in the red. Therefore spectral features have shifted by one order in the extracted spectra files. A new master wavelength solution was calculated (dated 20180323) and the songwriter config file updated accordingly. None Edit
2018-03-21 Water cooler was full of mineral deposits Mads and Antonio Water cooler Mads concluded it was dead but Antonio did his magic and made it work again. It is now back in operation. None Edit
2018-03-21 Web cam 1 was not working well Mads Web cams A new web cam was brought to the site and installed. A windows machine was needed for the installation (used one from IAC). Show Edit
2018-03-21 Visitors Mads and Andreas None Horsens Statsskole - 2F Show Edit
2018-03-20 Songwriter data extraction pipeline updated to handle the new CCD orientation Jens and Frank Spectrograph In the songwriter pipeline the possibility to rotate data frames was implemented. New pre- and over-scan regions were defined for frame trimming and bias statistics. A new master wavelength solution was calculated. None Edit
2018-03-20 The Andor CCD was reading out along the orders Mads and Andreas Spectrograph The CCD was unmounted and reinstalled (after cleaning the water pipes for minerals) rotated 90 degrees. Show Edit

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 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
2018-02-19 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
