General Description

• Goal of  these observations  is to determine  the spectral  types (and
  approximate ages) of HD_123356 A/B and CD-43_344, as well as to search
  for  H_alpha  emission.  Both  targets  show  circumstellar matter  at
  mid-IR wavelengths.  A spectral type  of G2V is given for HD_123356 in
  SIMBAD, but this is the  integrated spectrum of both components.  From
  SOFI  images the  B  component seems  to  be a  very  late type.   The
  spectral class of CD-43_344 is uncertain.
  
  The secondary in  the HD_123356 system is located at  posang = 126 deg
  in 2.5" distance,  but it  is outshined by  the primary in  the R-band
  finding chart.  In the K-band chart the separation is better seen, but
  note that in the infrared the B component is the dominant source.
  
  Visual magnitudes:
  
    CD-43 344        V =  9.4 mag
    HD 123356 A	   V = 10.0 mag
    HD 123356 B	   V = 12.2 mag		r = 2.5"	posang = 126
  
  No finding  charts were submitted  for the standard stars  LTT_377 and
  CD-32_9927,  which are  from the  frequently used  list  of "official"
  EMMI/ESO standards (with finding charts on the web and the NTT offline
  computer).

Waiver Requests

• No Waiver Request was submitted.

Critical Observing Condition Constraints

• None, besides the weather constraints given in each OB.

Time-Critical Aspects

• None.

Special Execution Requirements

• Spectroscopic acquisitions should be made  at the parallactic angle as
   
  defined in each OB.
  
  For the  two components  of  HD 123356  only one STD is  provided  per
  grism,  since a sequence  of Component A - STD - Component B  is short
  and can be completed in 40 minutes.  Therefore the standard  should be 
  observed together with both components of HD 123356.
