Estimated Total Execution Time (hours, including overheads)

• 11:59:00

General Description

• 12 hours have been allocated to this program.
  Uranus can be observed at airmass lower than 1.3 about 4h/night in the specified
   period.
  The Programme is therefore defined in 4 runs (A to D).
  Three of them contains 5 OB, three on the Uranus moving target (1h long-each) and
   2 for PSF/calibration of a standard star near the target, at the beginning and end
   of the run. 
  The smallest one only contains 3 OB, two on target,and starting with a standard
   star for calibration/PSF.
  
  The target RA and DEC are let to 0. There are given in the ephemeris file with one
   day time interval at 4h TU.
  
  Sensitivity: A relevant criterium for the required quality of sky in infrared would
   be the sensitivity, which we would like to have at about 60 mJy for the small field
   used.
  
  Findings charts: Uranus is an 4 arcsec-extended target observed with the VISIR instrument.
  There should be non confusion to detect it in the FOV.
  
  Differential motion: Uranus actual differential motion is 0.36 arcsec/hour in RA
   and 2.16 arcsec/hour in DEC. These values are put to 0 when entered in the planet
   OB target field.

Critical Observing Condition Constraints

• As we try to detect Uranus rings in infrared, we need to have a good sensitivity
   in the small field at about 50-60 mJy in the filter Q2 as specified in Table 2 of
   VISIR user manual.
  Wealso want ot have a PSF for each run.

Time-Critical Aspects

• Uranus observable at good airmass and 4H-long runs and closest to the
   Sun and Earth at the end of period 77.
