INAF LBC+MODS queue observing and AO PISCES, 2012 June 21-22
Observer: C. Arcidiacono, R. Briguglio, K. Boutsia, M. Faccini, F. Vitali
Telescope Operator: S. Allanson
Support Astronomer: D. Thompson
Instrument: LBC + PISCES
Clear skies at the beginning of the night and the average wind is 6m/s.
The night is dedicated to Pisces. We open up early (1:30UT) to do narrow band flats.
The seeing and the wind have been decent for the whole night.
No major problems with the AO system. Once the msgd crashed and they had to restart the secondary. We also had a couple of "shell rips" but we did not loose a lot of time.
Three more projects were completed tonight with Pisces.
At the end of the night, during twilight, we switched to LUCI to get some calibration frames in J and Ks of M15, for an older AO project.
|| J, Ks
|| 20min+sky / 2min Ks
|| ~4min x fliter + sky
|| FeII, 2.14um, Ks
|| ~30min x filter/ 5min Ks + sky
|| 3min x filter
|| calibrations with LUCI for an AO project
2.14continuum flats with Pisces
Telescope is collimater and we can send the first preset (Fiore - Mrk231)
- dimm seeing 1.1" - GCS seeing 1.1"
- loop closed
start with science block
- failed during offset - have to close the loop manually
send the preset again
- the quality of the first images was not very good
- we had to manually adjust the autogain
repeat block of images
no star on the guider for an offset position - but the loop is closed so we keep taking data
the loop opened but we are taking sky frames
once we offset back tothe target, it finds the star on the pyramid, the loop closes and we can go on
ACE preset to go back to the target after the sky frames
not Wavefrontsensing - power cycle the AZcam server again??
send preset again with autocollimate - now it seems to be working
we obtain also a block of Ks images because the seeing is better than the previous nights.
preset cancelled because the shell ripped!!
send active preset for calibration star AO534
Slewing to Barberi (KIC1086)
- preset cancelled because the shell ripped
- MessageDemon off-line
problem solved - sending a preset
science block starts
- we take also some longer exposures (10sec) where the center is slightly saturated
Slew to PCygni (Ragazzoni)
- test images to decide the dither pattern
we start the science block
loop open - try to close it manually
loop closed again - we start the script again with less offsets
send the offset with 30deg rotations
wrong PA in the sent offset
start science block at 30deg
acquireRef failed while we were sending a preset in track mode
sky frames for the PCygni project (Ragazzoni)
10:14 SWITCH TO LUCI
Slew to M15 for photometric calibration frames with LUCI
start script for J band - 10 sec exposures
- dimm seeing 1.0" - GCS seeing 0.6"
start script for Ks band - 5sec exposures
- images on Luci are elongated
start script for J band - 5sec exposures
start script for Ks band - sky frames a bit offset
start Ks flats (low - 2000counts)
J flats (low -1000counts/high -5000counts)
start Ks flats (high - 5000counts)
park telescope at zenith to get the Pisces flats ( J,H,Ks)
pisces stopped while we were taking flats - telnet connection is not responding
send scripts for darks (both for LUCI and Pisces)
13:26 END OF RUN!!
