Details

3:30 the to opens the dome, the sky is clear now

3:42 slewing to standard GD191
  • acq mods1r.20190131.0002-3, mods2r.20190131.0004-5
  • 3:46 dimm seeing 2"
  • sci mods1r.20190131.0004-6, mods2r.20190131.0006-8 red grating
  • 3:55 dimm seeing 1.5"

4:02 slewing to DeCarli field
  • acq mods1r.20190131.0007-9, mods2r.20190131.0009-11
  • 4:04 left side did not find guide star, check pointing, problem solved at 4:09
  • 4:12 seeing improving dimm seeing 1.3", fwhm on guider 1.1"
  • 4:21: dimm seeing 1.1"
  • sci mods1r.20190131.0011-12 ; mods2r.20190131.0013-14 offset6
  • 4:39 dimm seeing 1.2"
  • waiting to send the 7th offset, clouds, offset 6 is fine

6:50 the sky looks good now, the to opens the dome

6:55 slewing to Gilli program, mask 33
  • acq mods1r.20190131.0013-16 ; mods2r.20190131.0015-18
  • stop for collimation at 6:58, sending again the script 7:07
  • seeing 1.1" at 7:14
  • 7:20 some clouds coming in, we wait before sending the spec script
  • 7:29 sending spec script, clouds are gone
  • 7:32 fwhm on guider 0.8"
  • 7:34 variation of the guide star flux in the first exposures, some cirrus, check first exposures n. 1r17,1b2, 2r19, 1b2 , but we see some spectra
  • 7:51 dimm seeing 1.1", fwhm on guider 1", some clouds, but the flux of the guide star now is fine
  • 8:08 clouds again coming in guide star dimming by 2 mag, also second exposure affected by clouds, 8:15 we wait a bit, from the satellite it looks clear
  • mods1r.20190131.0017-18, mods1b.20190131.0002-3 ; mods2r.20190131.0019-20, mods2b.20190131.0002-3 affected by clouds but we see some spectra
  • 8:27 starting again integration, guide star is ok, dimm seeing 1.1", fwhm on guider 0.9"
  • 8:36 guide star ok, dimm seeing 1.1", no clouds mods1r.20190131.0019-24, mods1b.20190131.0004-9 ; mods2r.20190131.0021-26, mods2b.20190131.0004-9 good
  • 9:10 seeing 1"
  • 9:42 image 23 in red channel of mods2 looks strange, mods2r.20190131.0023.fits not good do not use
  • 9:57 image mods2r24 is ok
  • 10:03 dimm seeing 0.9"
  • 10:25 seeing 0.9", no clouds

10:45 slewing to Gilli program, mask 45
  • acq mods1r.20190131.0025-27 ; mods2r.20190131.0027-29
  • 10:54 dimm seeing 0.9", fwhm 0.8" on guider, no clouds
  • sci mods1r.20190131.0028-30, mods1b.20190131.0010-12 ; mods2r.20190131.0030-32, mods2b.20190131.0010-12
  • 11:50 dimm seeing 1.2"

12:14 slewing to Moretti A1
  • acq mods1r.20190131.0031-33 ; mods2r.20190131.0033-35 red channel of mods2 has some weird path in the upper part of image 34 and 35, the target is in the central slit and the spectra should be not effected by this strange pathern, we keep going with science
  • sci mods1r.20190131.0034-36 ; mods2r.20190131.0036-38
  • 12:41 dimm seeing 1.1" no clouds
  • 12:43 confirm spectra in the red channel is good, the strange shape in mods 2 red is in the upper right quadrant and does not affect the spectra of the target

14:10 starting MODS calibration Gilli mask 33 and 45
