General Description

• Imaging and Spectroscopy of Asteroid/Comet Elst-Pizarro, a moving target.
   The program asks for RI imaging and LSS spectroscopy of the object. Besides the
   two asteroid OBs, a solar analog star is to be observed for calibration purposes.
   
  
  Run A should be done before Run B.
  
  (1) It is advantageous to perform all OB s during the same night, in particular
   the ones for the moving target.
  
  (2) When performing both OBs of the moving target during the same night, it is recommended
   to perform the imaging OB of the asteroid before the spectroscopyone.
  
  (3) Before executing the OB on the moving target please enter in the OB 
      ==> RADEC of the asteroid at the epoch closest in time to the expected start
   time of the 			OB
      ==> the motion rates in RADEC at the epoch closest in time to the expected
   start time of 			the OB
      ==> the rotator position angle which is "MINUS*PSANG" value in the table
   
  Ephemeris: the attached ephemeris file lists for 15min time tags in UT the RADEC
   of the asteroid, its RADEC motion rates, the airmass, the apparent visual magntiude,
   the position angle of the tail direction (PSANG).
  
  Finding chart: No finding chart is prepared, instead we provide an image of the
   appearance of the asteroid. The motion range of the object is too wide to be reasonably
   covered by traditional finding charts and - more important: 1) for imaging the ephemeris
   precision is good enough (a few arcsec) to allow accurate pointing and 2) for spectroscopy
   the target is easily recognizeable since it has a long and narrow tail (see the
   attched image).
  
  Solar analog star calibration: Ideally to be done during same night as the asteroid
   spectra. Star is of G2V, 8mag in V.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• Try to execute all OBs during the same night.  Since the target is moving,
   please before observing enter the coordinates and the proprer motion given in the
   attached ephemeris.
  Please for the spectroscopy part enter also the angle of the rotator (equal to -
   PsAng in the ephemeris) in order to have the tail along the silt.

Time-Critical Aspects

• Please execute this program as sson as possible, since the comet was active
   few weeks ago.
