Estimated Total Execution Time (hours, including overheads)

• 3.0 h

General Description

• Fast PMOS of a moving target with time constraints. The target is a Saturn
   satellite, Iapetus. Please take care of entering the right coordinates and the additional
   tracking velocity according to the ephemeris file provided. Please execute the OBs
   within the time windows, which are clearly indicated in the OB name. Since target
   is moving, we do not provide finding charts.
  OB no. 356316 has priority over OB 356313, and OB no. 356315 has priority over OB
   no. 356312.

Waiver Requests

• Waiver 383.C-0058A.01.WAV requested and approved to use non standard readout
   mode.

Critical Observing Condition Constraints

• None

Time-Critical Aspects

• The OBs should be executed within three time window clearly indicated
   in the OB names, i.e.
  
  
  - From 2009-03-29 UT 00:00 to 2009-04-10 UT 23:59 (2 OBs: 356316 and 356316)
  
  - From 2009-05-09 UT 00:00 to 2009-05-30 UT 03:00 (2 OBs: 356312 and 356314)
  
  - From 2009-06-16 UT 23:00 to 2009-06-28 UT 23:00 (1 OB: 356314)
  
  
  The OBs within the same time-window should NOT be executed during the same night.
   If possible at all, the best thing would be to have the OBs pertaining to the same
   time windows executed at a distance of at least 3 nights, but this is not a must.
   
  
  OB no. 356316 has priority over OB 356313, and OB no. 356315 has priority over OB
   no. 356312.

Special Execution Requirements

• This is a moving targets. RA and DEC, as well as differential tracking,
   must be entered manually accoding to the ephemeris file.
  
  If OB execution is interrupted for any reason, and cannot be resumed immediately
   or within a few minutes, then the entire OB must re-executed.
  
  Acquisition and through-slit are best obtained with a narrow band filter to avoid
   saturation. In the OB we have indicated H alpha, but if this filter is not mounted
   at the instrument, fell free to use another one.

Special Calibration Information

• We do not request special calibrations. The usual standard star for linear
   polarization can be obtained with any readout mode and any slit-width, provided
   same grims and filter is used.
