2019-01-18 Number of ThAr lines found decreased rapidly indication a bad light bulb Frank, Antonio and Mads Spectrograph Antonio changed the ThAr light bulb to a new one which helped. Show Edit
2019-01-14 During Denmarks victory vs Saudi Arabia (34-22) in the Handball world cup some tests and a new pointing model was made Mads Telescope Tested the altitude problem in the other nasmyth (LuckyCam side) and the effect is also present there. Afterwards a new pointing model was made using 30 stars. Result: 1.02" RMS. Not perfect but hopefully better. None Edit
2019-01-13 Pointing model seems off by too much Mads Telescope From 2 UTC we did not acquire many targets. In the morning I manually set offsets in ZD to -25 and we acquired the targets again. Guess it is time for a new pointing model... Attached is the ZD offsets during the night. Show Edit
2019-01-08 Cleaning of M1 IAC's Instr. Maintenance Team and Lucia Telescope Standard cleaning (washing) of the SONG primary mirror None Edit
2019-01-06 Telescope continued to be pointed away from target Mads Spectrograph Finally the problem was solved. The implementation of the slit location was some times failing setting the slit offsets to 99... This should now be fixed. None Edit
2019-01-03 Failure in command to telescope made observations stop Mads Software God does not want us to observe Procyon... A failing command to the telescope (never happened before) made the obs scrip hang. None Edit
2018-12-28 No observations from 00:45 UTC Mads Servers Servers at Central had problems and the conductor did not insert new observations and was hanging. None Edit
2018-12-21 Problem guiding on the stars. telescope would move away from star right after acquisition Mads and Frank Telescope and guiders Tried many things but nothing worked. It seems to be a problem with the M8 piezo controller but not sure. None Edit
2018-12-17 Remote observations of the Moon Mads none Remote observations of the Moon as preparations for lunar eclipse observations in January. Show Edit
2018-12-03 Public outreach from 19:30 - 20:00 UTC Mads None Stopped observations and did some remote observations using SkyCam2 None Edit
2018-12-02 slit guider was moving target out of FOV affecting: HIP 10654 and HD 19438 Mads guiders Restarted the slit guider on sstenerife as obs None Edit
2018-11-26 Public outreach from 19:30 - 20:10 UTC Mads none Stopped observations and did some remote observations using SkyCam2 None Edit
2018-11-24 compressor and Pipe( manguera) Antonio P. And Anyi Telescope The air compressor was changed and, (10 Mt of pipe with incorporated terminals, new LeroyMerlin) Show Edit
2018-11-24 Telescope did not startup correctly at 3 UTC. The valve in the new compressor was not opened and the telescope raised and "pressure not reached" error at startup. None Edit
2018-11-24 compressor and Pipe( manguera) Antonio P. And Anyi Telescope The air compressor was changed and, (10 Mt of pipe with incorporated terminals, new LeroyMerlin) Show Edit
2018-11-04 Observations did not start correctly at sunset Mads, Frank Computers Frank tried to get things working... Mads saved him. The problem: slit-guider hanging -- rebooted from sstenerife ... NOT from hw anymore ... None Edit
2018-11-02 Not observing early and after too high wind Mads Telescope Wind speed was above 10 m/s and coming from east. Early I powered on and moved the telescope away from wind and opend the dome. Later it happened again and the monitor waited until wind from east was below 10 m/s None Edit
2018-10-30 pointing problem above 81 degrees in altitude Mads Telescope Tested the pointing model and mecanics by tracking a star blindly from below the 81 to above. SkyCam images whould show if the telescope it self was moving but it did not. Weather turned bad around the time when it was interesting. Show Edit
2018-10-28 Opened the PST Mads and Frank Spectrograph The PST was opened to measure for a new motor-slide for fibres Show Edit
2018-10-26 Visitors Mads Spectrograph SONG workshop 2018 Show Edit
2018-10-25 GPS error at startup from 23 to 4:45 UTC Mads GPS Moved the telescope manually and restarted the monitor. None Edit
2018-10-16 Did observations with SkyCam2 from 20 to 21 UTC Mads none acquired images of the Eagle Nebula... The Moon was close. None Edit
2018-10-14 Did observations with SkyCam2 from 20 to 22 UTC Mads none acquired images of the Eagle Nebula... The Moon was very close. None Edit
2018-10-13 Slit guider stopped working at 4 UTC meaning we only blind tracked from then on. Mads Guider Asked the operator (Paula) during the following day to power cycle the guide camera. She was very helpful. None Edit
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 STELLAs dust sensor stopped working at 1 utc Mads None Disabled the dust sensor in the standard way at 4 utc None Edit
2018-04-26 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
2018-04-25 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 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
2018-04-12 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
1970-01-01 Washing of the primary mirror IAC's Instr. Maintenance Team and Lucia Telescope Routine washing & cleaning of the SONG primary mirror None Edit
