Estimated Total Execution Time (hours, including overheads)

• 2hr 45mins

General Description

• The observations are part of a continuing spectroscopic and photometric
   monitoring campaign 
  designed to follow the evolution of 2 LBVs through what we expect to be giant outbursts.
   As such we have used the same OBs and finding charts from our proceeding run (ID
   079.D-0769 - hence  the label on the finding charts) which we found to yield excellent
   S/N observations.
  
  Note that given we need to analyse the whole spectrum (composed of two segments
   for both targets and standards) in order to extract information we ask that the
   two  OBs for each of  the targets and associated standards be executed as close
   together in time as possible, given that the targets are variable on timescale of
   weeks (and hence data taken at different times may not, a priori be 
  combined).
  
  So we would request the following 4 OBs be taken contiguously:
  
  355800 G24.73 (target) - central wavelength = 2.16 microns
  355802 G24.73 (target) - central wavelength = 2.10 microns
  355806 HD171279 (std for G24.73) - central wavelength = 2.16 microns
  355812 HD171279 (std for G24.73) - central wavelength = 2.10 microns
  
  and likewise the following four taken contiguously
  
  355803 HD177047 (std for AFGL2298) - central wavelength = 2.16 microns
  355805 HD177047 (std for AFGL2298) - central wavelength = 2.10 microns
  355805 AFGL2298 (target) - central wavelength = 2.16 microns
  355811 AFGL2298 (target) - central wavelength = 2.10 microns

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• Please see general description regarding the execution of the OBs

Time-Critical Aspects

• Please see the General Description regarding the time critical aspects
   of taking the two OBs for 
  each  target (and the 2 OBS for the associated standard) as close together in time
   (idealy contiguously) as possible.
  
  Note there is not requirement for observations to be obtained at a particular time
   of the semester.
