• 1.3

General Description

• This is a spectroscopic investigation of the fainter component in an eclipsing
   binary brown dwarf. The observation has to be carried out EXACTLY during the eclipse.
  
  Eclipse center is 
  on 21-dec-07 at 05:42 UT
  
  this means that the observation of one hour duration MUST start 
  on 21-dec-07 at 05:12 UT
  
  Please start this observation as close to 05:12 UT as possible.
  
  There will be a second spectrum taken a few weeks later during another eclipse,
   but only both observations together will provide scientific output (in case this
   failes, we can combine this exposure with observations to be carried out during
   later eclipses).
  
  It would be nice if the telluric standard could be observed before or after the
   2MASS0535 exposure, but it is not required.
  
  
  One question to the observer:
  Is it possible to please store the information from the exposure meter and include
   them in the data files or just send them to me? Because this is an eclipse observation
   it would help a lot to see if we actually observed during the center of the eclipse.

Waiver Requests

• Waiver 280.C-5012A.01
  
  for using the 830nm non-standard setup
  and to use OBs exceeding the 1h limit

Critical Observing Condition Constraints

• The main constraints come from the time-critical aspects. If any light
   comes from the object at that time, please observe it.

Time-Critical Aspects

• The observation of 2MASS0535 MUST occur during eclipse:
  
  Eclipse center is on 21-dec-07 at 05:42 UT.
  
  This means that the observation of one hour duration MUST start 
  on 21-dec-07 at 05:12 UT!
  
  Please start this observation on 21-dec-07 as close to 05:12 UT as possible!

Special Execution Requirements

• The exposure of 2MASS0535 should start exactly at 05:12 UT.
