General Description

• SCIENTIFIC OVERVIEW :
  
  We will observe the star HD189733 with SINFONI/SPIFFI in the simultaneous H+k mode
   with a spectral resolution of R=1500, in order to study the day and night side spectrum
   of the very hot Jupiter planet orbiting this star with a period of 2.219 days. We
   expect to obtain a very high SNR of 10,000:1 by averaging in the sepctral domain
   and in the time domain. 
  
  In order to observe the day side spectrum and the night side spectrum of the planet,
   2 time critical runs are necessary : one during the transit or occultation of the
   star by the planet (run A, UT date : July 30, 2006) and during secondary eclipse
   (run B, UT date : 29 August, 2006) when the planet passes behind the star. 
  
  TIME CONSTRAINTS:
  
  We need to start 2 hours before center of eclipse and observe until 2 hours after
   the central eclipse, with a total duration of the observations equal to 4 hours
   (including overheads).  For this run A, we should start no later than (UT times):
  
  2006-07-30T02:55:00 
  
  and observe until
  
  2006-07-30T06:55:00
  
  
  EXPOSURE TIMES:
  
  According to the exposure time calculator for SINFONI with AO, the detector will
   not saturate with 3 sec, when the seeing is 0.5 arcsec, airmass=1, platescale=25mas,
   spectral type of target K0-K2 and Kmag=5.54.  In order to optimize the observations,
   the exposure time should be adjusted (this may not be possible in service mode).
   Just as an indication, when the seeing increases to 0.8 arcsec, the DIT can be 4.8
   sec without saturation. 
  
  
  SKY FRAMES:
  
  Four sky frames are included. They should be taken with an offset of RA=14arcsec,DEC=13arcsec
   from the central position of the object, and the observations of the target should
   be done always at the same original position. 
  
  Thanks in advance for the observations to be done and a lot of luck for the weather
   and seeing!

Waiver Requests

• A Waiver Request was submitted to use the fast acquisition template for
   AO to avoid saturation due to the brightness of our target K=5.54 mag. Moreover,
   to enhance efficiency (minimize overheads), a continuous observing block of 4 hours
   was requested.

Critical Observing Condition Constraints

• During the run, the target is observable with airmass < 2 and the moon
   is always 45 degrees away. Thus, the critical observing conditinons are set by the
   AO system limits.

Time-Critical Aspects

• We need to start 2 hours before center of eclipse and observe until 2
   hours after the central eclipse, with a total duration of the observations equal
   to 4 hours (including overheads).  For this run A, we should start no later than
   (UT times):
  
  2006-07-30T02:55:00 
  
  and observe until
  
  2006-07-30T06:55:00
