Estimated Total Execution Time (hours, including overheads)

• 5 hours

General Description

• Observation goal:
  
  (1) To image Saturn in 7 filters: PAH1, SIV_2, NeII_1, 7.9, Q1, Q2, Q3.  Repeat
   to capture feature rotation on Saturn's disk.  Saturn aligned so both planet and
   ring ansae sit on the array.  
  (2) Spectroscopy along the central meridian (A) HR 8.02 micron, (B) HR 12.81 micron
   and (C) MR 11.6 micron.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• Weather flag should be set to P.

Time-Critical Aspects

• Should be conducted in April 2008 to allow time for repeated imaging sequences
   in May and June (also this proposal). Saturn is available in the early part of the
   night, 1930-0100 Local Time.
  
  We request that the observation blocks are executed in the following sequence:
  
  1.  MOV_img_saturn_apr08_set1
  2.  CAL_img_star_apr08_set1
  
  At a later time (5 hours later, or at multiples of 10 thereafter to capture Saturn's
   opposite hemisphere):
  
  3.  MOV_img_saturn_apr08_set2
  4.  CAL_img_star_apr08_set2
  
  Spectroscopic observations along Saturn's central meridian can be performed independently
   of one another at any time that Saturn is available (preferably at low airmass).
    There is no explicit order to the spectroscopic OBs, but observations of the target
   and of the spectral calibrator must be taken concurrently.

Special Execution Requirements

• SEQUENCE TIME:
  The total sequence time for imaging on each filter is 60 seconds. Within each imaging
   OB, each filter is repeated twice with an offset of few pixels to correct for bad
   pixels. Do *NOT* run the acquisition again, just offset the telescope by 3 pix in
   RA and 3 pix in DEC.
  
  Each spectroscopic integration should last 720s on Saturn and 480s on the calibration
   star.
  
  WEATHER FLAG:
  The weather flag must be set to P because Saturn is bright and would othrwise produce
   striping.
  
  POINTING:
  Pointing for Imaging: Planet disk should be centred, and rotated anticlockwise 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.
    Position angle and chopping angle have been set to 50, but the exact value will
   depend on the observational date.
  
  Pointing for Spectroscopy: Planet disk should be centred and rotated anticlockwise
   by 5-10 degrees to align central meridian with slit.  Position angle has been set
   to 7.
  
  Second chop position will be discarded, so ensure chop throw is sufficient to prevent
   overlap on the planet and rings.

Special Calibration Information

• Observations of standard star in all filters.
  HD87837  [pos 10:07:54.27  09:59:51.0]  V=4.381,[12]=17.570Jy
  Spectroscopic calibration via observations of alpha Hya, with beta Gem as a backup.
