General Description

• This program is a compensation for ToO time given the 2005 Jul 30 UT 
  from 02:27 UT to 04:17 UT. 
  
  The program is aimed at reconstructing accurately the short therm photometric 
  variability of the Uranian Irregular Satellite Prospero. The most important 
  target of our program in the evening the ToO occurred. 
  
  We plan to use for this FORS2 at UT1. The program shall best be 
  performed in the second half of September 2005. 
  
  The estimated magnitude for Prospero is R~23.5. The magnitude will change barely
   
  of 0.1 mag between August and September and exposure times do not need to be 
  adapted. This plan would allow to reach a relative accuracy of at most some 0.01mag
  
  The program consists simply of a sequence of exposures obtained keeping 
  Prospero at the center (within 1 arcmin) of the master CCD camera of FORS2.
  
  The sequence of frames is R B R V R I R ... R, each exposre of 300 secs. 
  The sequence is accomodated in two OBs named MOV_PROSPERO_SQ0 and 
  MOV_PROSPERO_SQ1 to be executed in sequence (= one after the other)
  The MOV_PROSPERO_SQ0 shall be executed first.

Time-Critical Aspects

• NA

Special Execution Requirements

• =======================================================================
  TSZ: I have set the airmass constraints to 1.7 - the user selected 1.0!
  =======================================================================
  
  The speed for differential tracking shall be fixed at the beginning of
  the sequence and does not need to be changed during the observation. 
  
  WARNING:
  ========
     In the ephemerids file the columns for the additional velocities
     (4th and 5th columns) 
  
                   ARE EXPRESSED in ARCSEC/HOUR
  
     these values must be divided by 3600. to have the correct additional
     velocity to put in the OBs together with the proper position.

Special Calibration Information

• Standard stars in the list of those select for FORS2 calibration program
   are 
  sufficient. But we need to take at least a field before the beginning of the 
  sequence and one field at the end. Possibly the fields shall be selected in 
  order to span as large as possible the range of colours from negative (as 
  an example -0.1) to positive (as an example +0.6). This can be easily 
  accomodated within most of the standard FORS2 fields.
