General Description

• Start with the calibration star (2 wavelength settings).
                                                                                 
   
  Then do the acquisition on Jupiter's impact site (RA and DEC given in the ephemeris
   file, Cols 2 and 3). The impact site should appear as a very elongated region, brighter
   than the surroundings, maybe more clearly in the imager filter (SIV). If the impact
   site is no longer visible, determine Jupiter's center from the acquisition and apply
   a blind offset to reach the impact site. The position of the impact site relative
   to Jupiter's center is given in the ephemeris file (Cols 4 and 5). The position
   of the impact site (red dot) on the Jovian disk is shown on the finding_charts attached
   (at a selected few times on each possible date).
  
  The differential motion, corresponding to the correct date and UT time, must be
   entered as given in the attached ephemeris file (Cols 6 and 7). This differential
   motion includes that of Jupiter PLUS that of the impact site relativelt to Jupiter's
   center, so that the telescope will track the impact site.
     
  Then start science integration with the slit centered on the impact position (=
   Position 1) at wavelength 1. We also need two other positions offset from Position
   1 (=impact site) by the following quantities:
  . Position 2: -0.3" in RA direction; +0.7" in delta
  . Position 3: +0.3" in RA direction; -0.7" in delta
                                                                                 
   
  So the whole sequence is:
  . do the acquisition on the impact site or go to it from Jupiter's center(Position
   1)
  . integrate on Position 1, wavelength 1
  . apply a blind offset to move to Position 2 and integrate at wavelength 1
  . apply a blind offset to move to Position 3 and integrate at wavelength 1
  . change the setting to wavelength 2, integrate on Position 3
  . apply a blind offset to move to Position 2 and integrate at wavelength 2
  . apply a blind offset to move to Position 1 and integrate at wavelength 2
                                                                                 
   
  If time is left, continue integrations at wavelength 2 on Positions 1, 2 and 3

Critical Observing Condition Constraints

• None

Time-Critical Aspects

• The observations should be conducted at least 10 days after 283.C-5046(A)
   if possible. Jupiter's impact site can be observed in one of the following periods
   (or later if required):
  - 13 September 2009: 0h45 - 2h45 UT
  - 15 September 2009: 2h15 - 4h15 UT
  - 17 September 2009: 4h00 - 6h00 UT
  - 17-18 September 2009: 23h45 - 1h45 UT
  - 20 September 2009: 1h30 - 3h30 UT
  - 22 September 2009: 3h00 - 5h00 UT
  - 22-23 September 2009: 23h00 - 1h00 UT
  - 24 September 2009: 4h45 - 5h30 UT
  - 25 September 2009: 0h30 - 2h30 UT
  - 27 September 2009: 2h15 - 4h15 UT
  - 29 September 2009: 3h45 - 5h15 UT
  - 29-30 September 2009: 23h45 - 1h45 UT

Special Execution Requirements

• The differential motion (Diff RA and Diff dec) in arcsec / sec are given
   in the attached ephemeris file. Note that they include the motion of Jupiter PLUS
   that of the impact site relative to Jupiter's center. They must be used for the
   correct date and time so that the telescope tracks the impact site.

Special Calibration Information

• ---(Empty)---

ToO Information

• New impact on Jupiter (lat 56degS, long 303W). Position with respect to
   Jupiter's center can be found in the attached finding charts (red dot) and is given
   in the ephemeris file in arcsec (Cols 4 and 5). The absolute RA and dec of the impact
   site are also given in the ephemeris file (Cols 2 and 3).
