Estimated Total Execution Time (hours, including overheads)

• 16

General Description

• The goal of this 16 hours observing run is to obtain images of Uranus
   at 13 um (NeII-2) and 19.5 um (Q3) with adequate signal to noise for reduction.
    In particular, we are searching for stratospheric variability in the NeII-2 filter,
   requiring two sets of images separated by 8-9 hours to capture both hemispheres
   of the planet.  
  
  For stability of pointing and tracking we have separated the NeII-2 observations
   (7200s on each hemisphere) into two sets of 4 1800s OBs.  It would be best if the
   four OBs were run sequentially, followed 8-9 hours later by the second set of four.
    If reacquisition is not necessary for each of the four OBs, please extend the integration
   time (as our goal is high SNR).
  
  The single desired image of Uranus at Q3 has been subdivided over 8 observation
   blocks (for stability), each taking 55 minutes to execute.

• A Waiver Request was submitted.

Critical Observing Condition Constraints

• Airmass < 1.5
  Very low humidity
  Good seeing <0.8 if possible
  
  The goal for the second NeII-2 imaging set is to observe the opposite hemisphere
   of Uranus, when the planet has rotated by 180 deg. in longitude.   This corresponds
   to ~8-9 h at our latitude of interest.  This is best accomplished by observing the
   intial imaging sequence in the early evening and repeating 8-9 hours later in the
   morning.

Time-Critical Aspects

• These observations were scheduled in August 2009 to maximise the available
   time for the target.  Uranus needs to be at airmass <1.5

Special Execution Requirements

• Please make every attempt to place the positive and negative images of
   Uranus in regions of the detector with limited bad-pixels.  
  
  We propose to observe, by priority :
  
   (1) MOV_ura_hemis1_NeII-* (first hemisphere of NeII-2 imaging, 4 hours). 
   (2) MOV_ura_hemis2_NeII-* (second hemisphere of NeII-2 imaging, 4 hours). 
   (3) MOV_ura_Q3-* (one set taking ~8 hours, hemisphere doesn't matter)
  
  Please execute (2) 8-9 hours (plus multiples of 17 thereafter) after (1) so that
   we observe the opposite hemisphere of Uranus.  For example, if starting observations
   at 1900-2000, then the observations could be repeated by 0300-0400 for the opposite
   hemisphere.  Alternatively, if observations are made at 0100, then they may be repeated
   at 0200-0300 the following night.
  
  The eight subdivisions of the Q3 image would be best obtained SEQUENTIALLY.

Special Calibration Information

• We request that standard imaging of stars be supplied (at similar airmasses,
   where possible) to allow us to characterise the PSF.
