Estimated Total Execution Time (hours, including overheads)

• 7.0

General Description

• The goal of this first Neptune observing run in period 083 is to image
   Neptune's atmosphere in PAH1, 7.9, NEII-1 filters (3.5 hours), and then repeating
   the same observations six hours later (if airmass and weather permit) when Neptune
   has rotated by 180 degrees to characterise the opposite hemisphere.  The goal is
   to search for spatial variability and rotation, particularly in the polar region.
    
  
  Our primary requirement is good signal to noise, so please extend integration times
   (where overheads have been overestimated) to fill the available seven hours.

Waiver Requests

• A waiver request was submitted.

Critical Observing Condition Constraints

• Airmass < 1.5
  Very low humidity
  Good seeing <0.8 if possible

Time-Critical Aspects

• To maximise possible observing time (and to allow sufficient time before
   execution of 083.C-0163(B)), these observations should be executed in August 2009.
  
  For a particular hemisphere, it would be best if all three filters were acquired
   sequentially.
  
  The goal for the second imaging set is to observe the opposite hemisphere of Neptune,
   when the planet has rotated by 180 deg. in longitude.   This corresponds to ~6 h
   at our latitude of interest.  This is best accomplished by observing the intial
   imaging sequence in the early evening and repeating 6 hours later in the morning.
    
  
  If it is not possible to observe 6 h later, please, be ensure that the second observation
   observes the opposite side of Neptune.  This can be done on the successive night,
   i.e. 24h later, PLUS or MINUS a 6-hour delay, e.g. an initial observation made at
   0400 local time can be repeated on the next night at 2200; an initial observation
   made at 2100 local time can be repeated at 0300 the following night (i.e. 30 hours
   later) if weather or other problems prevent a repeat with a short 6-hour delay.

Special Calibration Information

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