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 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
2017-09-12 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
2017-09-09 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
2017-09-06 Stella dust sensor not working after scheduled power failures Mads weather station normal work around. Stopped dust reader restartet weather station software which then sets dust values to zero. No dust on web cams. None Edit
2017-09-04 Central was down Mads Servers Rebooted central (virtual machine running in Aarhus and running the central database) None Edit
2017-08-31 In the moning the conducter did not insert beacuase of database problems Mads Servers Fixed some things in the code and elsewhere which made it work again None Edit
2017-08-29 At UT~00:25 discovered that the telescope was tracking but far out of focus (1.99mm), OR req = 22991 Frank Spectrograph Added 0.8mm to the telescope focus offset in Astelos - This cured the problem and full pupil illumination and guiding proceeded as normal. None Edit
2017-08-18 Telescope did not want to move from 04:40 to around 6:00 UTC Mads Telescope Nothing None Edit
2017-08-16 Dome not aligned with telescope - Noticed at UT~2130 Frank Dome Powercycled the dome and cleared errors in Astelos. this worked for the next target. None Edit
2017-08-16 Telescope powered itself off.... ? After the previous log entry, the next object (Arcturus) was observed. However after Arcturus the telescope again did not point out of the dome. Frank Telescope and dome stopped or_scheduler, monitor and tcs_comm. Parked and closed the telescope manually with astelos and rebooted the dome controller. Started tcs_comm, and monitor. this started everything again and found the first object None Edit
2017-08-15 Errors could not be cleared - Astelos reported Emergency buttons pressed for flap,slit,dome az Frank Checked that no one was in the dome and cleared the errors in Astelos. this worked. None Edit
2017-08-14 SkyCam-2 imaging Mads None Took some nice pictures - M16 and M51 None Edit
2017-08-10 Motor controller problem from 22 UTC Frank, Mads Spectrograph Not detected before the morning. Motor for slit was reporting -moving- constantly which caused all ORs to fail. None Edit
2017-08-07 Stella dust sensor online again Mads Weather station Started the dust daemon again and restarted the weather daemon None Edit
2017-08-01 Stella dust sensor stopped working Mads Telescope Disabled it since there were no dust None Edit
2017-07-31 Visitors Mads None Marley Dahl Fredslund, Bettina Dahl Laursen and Mads Fredslund Andersen Show Edit
2017-07-31 Secured light shielding at the blue spectrograf - coude entry Mads Blue spectrograf and Coude Added some extra gaffa tape to secure the plastic cover around the blue spectrograf None Edit
2017-07-31 Removed and inserted again the shutter electronic box Mads Spectrograph Unplugged the connections to the box and opened it to photograph the interior to send to Ezequiel Show Edit
2017-07-29 Dome was offset after shutdown and did not startup correctly - From 22:30 utc Mads Dome Cause: the telescope did not power off because the dome never reached the park position. The monitor expects the telescope to be powered off after bad weather and did not startup afterwards. Show Edit
2017-07-26 Dome not moving from around 23:20 UTC - vignetting Mads Dome None - it was not detected. Show Edit
2017-07-24 ThAr bulb replaced Mads Spectrograph A new ThAr bulb replaced the old on. New one has serial number: HMC0304. The number of lines was clearly different. None Edit
2017-07-22 VM song.sscentral.prv was hængning sinece around 11 o'clock yesterday meaning the conductor did not run the whole night. Mads None Restarted song.sscentral.prv and started the conductor again None Edit
2017-07-18 Missing light in coude and vignetting of pupil Mads Telescope No light went to coude at startup. I found stars though. Pointing model (PM) was of. Moving M3 a couple of times reduced the offsets but not enough. I manully added some mean offsets to the observing scripts until I have time to do a full PM. Vignetting of pupil might be plastic cover between Blue Spectrograph and Coude path. None Edit
2017-07-18 No light to coude Mads Telescope M3 was not located correctly. Attached is before and after rotation of M3 the pupil image. Show Edit
2017-07-17 Serious problem with Paul Butlers iodine cell. Cannot fit data after 4th August. Suspect cause is that the temperature controller is not running properly. Frank Iodine cell from Paul Butler Emailed Mads, Pere and René, stopped the observations for MuHer with Pauls cell, and let the Conductor deal with the rest of the night. None Edit
2017-07-17 No light to coude Frank and Mads Telescope Tried several things and nothing heleped. We decided to close down at 00 UTC after hours of attempts to fix it. None Edit
2017-07-10 Telescope was below 16 degrees (which was okay). The monitor wanted to park the telescope but an observation started in the middle of the movement and telescope never got to park position. Mads None Code needs to be corrected None Edit
2017-07-10 Dome not aligned Frank Dome at ut=05:30 noticed dome was not aligned. Powercycled the dome controller ... this worked. None Edit
2017-07-08 Dome parked in wrong position Frank Dome Rebooted the dome controller and cleared all errors from Astelos manually. Will hopefully start up correctly on its own tonight. None Edit
2017-07-07 At sunset the both limit switch active error happened Mads Telescope Tried to do the things I could but it did not help. Skyped with Michael Ruder who helped out. None Edit
2017-07-07 scratch had only 288GB left of disk space Mads Servers Removed all data and extracted data up to the 1/7 2017 including skycam images which has provided 2.9TB free disk space. None Edit
2017-07-06 Test of blue spectrograph from 22 to 00 UTC Simon Blue spectrograph testing None Edit
2017-07-04 Errors were not cleared after power cycle of dome controller. Mads Telescope and Dome Cleared the two errors and restarted the monitor to allow observations right away. None Edit
2017-06-29 Dome flap open and pointinge ~50deg. from the wind direction with ~13-15m/s .. Frank Dome and flap Discovered this at sun_alt~-6 so closed the mirror covers with Astelos, but waited for the monitor to close down as normal (which worked fine). Show Edit
2017-06-28 Telescope was stationary after 4:20 UTC Mads Telescope went a bit below the software limit of 16 degrees which made it "stuck". Corrections to the code has been made and the telescope should be parked when this occurs in the future. None Edit
2017-06-18 Power failure at 21:35 UTC. Mads All This was not detected before the following morning. No SMS was sent out. The night operator was asked to check and he saw the DIF 3 relay was switched off. Show Edit
2017-06-15 Dome not aligned for the last few hours of the night. Frank Dome Manually moved the dome +/-50 deg in offset with Astelos - at some point the were 'serious errors' in astelos which I acknowledged ... after ~1 minute setting the offset to zero cured the problem. None Edit
2017-06-13 Scratch not mounted om kvmtenerife and vms Mads and Frank Servers Mounted scratch manually "mount -a" as root. This was an issue occurring after the power outage. None Edit
2017-06-12 Replacement stelco rack batteries Antonio Rack STELCO The tape in the photo is because it came broken, but does not lose acid. And the voltage is fine. (To lighten the change, left the wires of the previous battery is so the broken was seen.) Show Edit
2017-06-07 A disk for SODA was full and SODA was down. Mads, Rasmus, Ditte, Eric Servers Eric and Rasmus worked on it bur restoring from backup was slow and SODA was down during night which caused the conductor to fail obviously. None Edit
2017-06-05 Dome was offset again Mads Dome Power cycled the dome controller Show Edit
2017-05-29 Stellas dust sensor stopped working Frank Dust-sensor Disabled the dust-sensor as the weather looks great. None Edit
2017-05-05 Blue spec observations Christoffer Blue spectrograph test observations None Edit
2017-04-17 sstenerife down Mads servers Restarted sstenerife through iDRAC None Edit
2017-02-07 Test of blue spectrograph Simon Blue spectrograph test None Edit
