Estimated Total Execution Time (hours, including overheads)

• 2.5

General Description

• Observation Goal:  To image Saturn in 8 filters: PAH1, SIV_2, NeII_1,
   NeII_2, 7.9, Q1, Q2, Q3.  
  
  These imaging observations are then repeated 5 hours later to capture feature rotation
   on Saturn's disk.  A third short OB (imaging in just five of the filters) was included
   to maximise our integration time on Saturn, and can be executed independently at
   any time.
  
  Saturn should be aligned on the detector so that both the planet and ring ansae
   sit on the array.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• Seeing < 0.8" and airmass < 2.0

Time-Critical Aspects

• This second observation run should be conducted in May or June 2009 after
   execution of 383.C-0164(A). 
  
  The first eight-filter imaging set (MOV_img_saturn_may09_set1) should be conducted
   as early as possible during the night to allow for the second imaging set (MOV_img_saturn_may09_set2)
   to be conducted 5 hours later (or at multiples of 10 thereafter) to capture Saturn's
   opposite hemisphere.  The final set (MOV_img_saturn_may09_set3) is much shorter
   and can be executed at any time.

Special Execution Requirements

• SEQUENCE TIME:
  The total sequence time for imaging on each filter is 120 seconds. The GenericChopNod
   template was used so that manual offsets could be employed to avoid bad pixels and
   striping.
  
  POINTING:
  Pointing for Imaging: Planet disk should be centred, and rotated by approximately
   50 degrees so that east and west ring ansae fit diagonally across the array from
   bottom left to top right (50" width) as shown in finding charts.  Chopping Position
   angle has been set to 50 degrees (measured east from north) and rotator angle has
   been set to 50, but the exact value will depend on the observational date.  PLEASE
   CONFIRM THAT THESE ANGLES ARE CORRECT FOR ORIENTATION AS IN THE FINDING CHARTS.
  
  Second chop position will be discarded, so ensure chop throw is sufficient to prevent
   overlap on the planet and rings.

Special Calibration Information

• For imaging, we request standard VISIR calibration imaging of a nearby
   star (at the same airmass as Saturn) to characterise the PSF.
