General Description

• Primitive Dust in Oort Cloud Comet C/2004 B1 (LINEAR)
  
  Run A: EMMI imaging
  
  This is a simple point-and-shoot imaging program on a comet, a moving target. Saturation
   of the coma center must be avoided. Template offsets return comet to approx. start
   pixel position. For aborts: repeat complete template.
  
  IMPORTANT: The OB MOV_C2004B1_astrometry" should be taken before 9 April; the data
   should be made available to the PI immediately. The two OBs MOV_C2004B1_BVRI_night1/2
   are to be executed in two different nights. 
  
  For the comet position only approx. RADEC coordinates typical for the expected observing
   period (Apr. 2006) are given in the OBs, the differential velocity is set to 0.
   Both parameter sets need to be updated by the SM observer before execution of the
   OB. The rotator angle remains unchanged (0deg).
  
  Here is a brief cookbook instruction for the OB execution:
  
  - select OB to be executed
  - open attached ephemeris file
  - enter RADEC coordinates for epoch closest in time to start of OB (ephemeris columns
   RA and DEC)
  - enter differential RADEC velocity for epoch closest in time to start of OB (ephemeris
   columns Vel_RA and Vel_DEC)
  - do not change rotator angle of the OB
  - start OB

Waiver Requests

• No Waiver Request was submitted.

Critical Observing Condition Constraints

• Please perform OB "MOV_C2004B1_astrometry" before 9 April 2006 and release
   data immediately to PI; the data are needed for preparation of upcoming Spitzer
   observations of the comet in mid May 2006 with submission deadline on 10 April 2006.
  
  Please perform only one OB per night !
  
  Environmental conditions for astrometry: 
  Sky = THN
  Seeing = n
  Moon = f
  
  Environmental conditions for other coma imaging:
  Sky = CLR
  Seeing = n
  Moon = g

Time-Critical Aspects

• The OB MOV_C2004B1_astrometry should be executed before 9 April 2006 and
   the data should be released to the PI immediately, since they are required to prepare
   Spitzer follow-up observations scheduled for mid May 2006 (submission deadline for
   Spitzer is 10 April 2006).
  
  The OBs MOV_C2004_night1/2 should be performed in two different nights in February
   to April 2006.

Special Execution Requirements

• The central part of the coma must not be overexposed. Since comets are
   notoriously unpredictable in their brightness, we can't guarantee for sure that
   the carefully chosen integration times in the OBs will be safe against saturation
   of the cometary coma. If saturation occurs, feel free to shorten the integration
   time appropriately.
  
  Please execute only one OB MOV_C2004B1_night1/2 per night!
