Estimated Total Execution Time (hours, including overheads)

• 4.0 hours

General Description

• Run B will be triggered in response to any observed changes in Oval BA
   or other storm systems on Jupiter, one year after a close encounter with the Great
   Red Spot.  We will communicate directly with the observatory for the triggering
   of this run, providing information which may override the contents of this readme
   file.  Central meridian crossing times will be provided along with the trigger.
  
  In order or priority, the goals of this program are:
  
  1.  Imaging of Jupiter's southern hemisphere in 8 filters: 7.9, PAH1, SIV_2, NeII_2,
   Q1, Q2, Q3, NeII_1.  
  2.  Spectroscopy at MR10.1, MR10.3, MR10.5, HR8.02, and HRX 13.364 microns for the
   target, with the slit north-south along the central meridian.

Waiver Requests

• No Waiver Request was submitted, as this second trigger will achieve the
   goals of the original proposal.

Critical Observing Condition Constraints

• Seeing less than 0.8\" is desired.
  Weather flag P is useful for reducing horizontal striping over the detector.
  Ensure negative beam does not obscure the target region in both imaging and spectroscopy.

Time-Critical Aspects

• Ephemeris and rates have been supplied from October 1st through to December
   30th.  
  Jupiter central meridian crossing times for the feature of interest will be supplied
   with the trigger.
  
  Please execute the OBs in the following order (Finding charts are included to locate
   the targets): 
  
  TOO_MOV_spect_jup_MRHR
  TOO_MOV_img_jupiter_south (at approximately CM crossing).
  TOO_Mov_spect_jup_HRX_set1
  TOO_Cal_spect_star_HRX_set1
  TOO_Cal_spect_star_MRHR
  TOO_Mov_spect_jup_HRX_set2
  TOO_MOV_img_jupiter_north (finish two hours after CM crossing).
  
  These OBs have been prioritized so that the first few are the most important.

Special Execution Requirements

• Generic chop nod is used with two dither positions to remove bad pixels,
   but please try to avoid these if possible.
  
  POINTING: 
  The second chop position will be discarded, so ensure chop is sufficient to minimize
   overlap on the planet's southern hemisphere. 
  For southern hemisphere imaging, Jupiter should be centered right-left, with the
   southern limb some 3-4 pixels above the bottom of the field of view, chopping so
   as to avoid overlap of the positive and negative images on the southern hemisphere
   (see example in finding charts).
  For northern hemisphere imaging, Jupiter should be centered right-left, with the
   northern limb some 3-4 pixels above the top of the field of view, chopping so as
   to avoid overlap of the positive and negative images on the northern hemisphere
   (see example in finding charts).
  
  POINTING FOR SPECTROSCOPY: 
  Rotate slit so that it lies north-south parallel to the central meridian (see finding
   charts).
  North polar angle is 340.12 on October 1st, and variations are in the ephemeris
   table.
  Ensure negative beam does not obscure the feature of interest.
  
  HRX:  Two spectral OBs have been supplied, one for the centre of the feature, and
   the other offset 10" east or west to get a comparable 'standard' region of Jupiter
   (i.e. away from the feature of interest).

Special Calibration Information

• For imaging, we request standard star imaging to characterise the PSF
   at approximately the same airmass.  
  
  Spectroscopy of HD200914 is requested to calibrate our spectra.

ToO Information

• ToO will be triggered based on information provided by amateur astronomers.
    Triggers will include central meridian crossing time for the feature of interest
   and availability during the night.  The sequence of OBs is designed so that imaging
   occurs when the target is close to the central meridian.
