• 2.75hours

General Description

• This program is designed to obtain 2 spectra of 2 Luminous Blue Variable
   stars 
  separated by as large a temporal baseline as possible.
  
  For the purpose of the science we require both OBs for a single star to be executed
   
  in order for quantitative analysis of the data. Thus we prioritise that the 2 
  observations of AFGL 2298 (and associated callibration OBs) be made before observations
  of G24.73
  
  Note that while we have marked the slit position on the field the fields are not
   crowded and 
  so other positions could be accommodated.

Critical Observing Condition Constraints

• None

Time-Critical Aspects

• We have two approved runs for this program which we would ideally like
   to be spaced as far appart in time as possible during the semester. Thus we have
   suggested that run (B) be carried out in the period 1/4/07 to 30/9/07 and run (C)
   from 1/7/07 to 30/9/07, so that hopefully we 
  will have an observation made in each half of the semester.
  
  For each star we have 2 OBs detailing observations done at two different central
   wavelengths. We request that both observations of a single star be carried out as
   close together in time as possible in preference to one observation of each star
   in order to obtain a composite spectrum that is as near simultaneous as possible.
   
  
  Finally we suggest a minimum useful separation of 3 months between these observations
   and those detailed
  in  079.D-0769(B)

Special Execution Requirements

• None

Special Calibration Information

• Because we require high S/N and resolution spectra we request that a telluric
   standard anda
  and a flat be taken contemporaneously with each target spectrum. We have produced
   
  relevant callibration files for each of our two targets and have indicated within
   the 
  user comments which callibration OB belongs with which target OB. For completeness
   
  the relationship is:
  
  Target       Callibration
  AFGL 2298     HD 177047
  G24.73+0.6    HD 171279
