General Description

• The aim is to separate two ongoing planetary candidate Microlensing
  events in a crowded Bulge field from unrelated background
  sources with NACO-S27-JHK imaging to determine the combined source +
  lens flux. These observations will establish a reference
  epoch to be compared to a future epoch, where the events will have
  terminated.
  
  Together with the lens model for the light curve we then will be able
  to extract accurately the mass and projected orbit of the planet candidates 
  without the need for assuming a Galactic model.
  
  The earlier the observations can take place, the better the final
  constraints on the lens star and its planet. Ideally we would like to
  have the observations done before the 31st of August.
  
  
  We have requested the use of the laser guide star since this will
  offer the best results for our science. However, the observations are
  requested to be carried out as soon as possible to obtain data while
  the object is still slightly amplified by the microlensing events. If
  this would be made impossible due to long term technical problem with
  the laser, we can also use natural guide stars. 
  These (backup) guide stars are marked with R1 (first choice), respectively
  R2 (second choice) in the finding charts.

Critical Observing Condition Constraints

• We asked for seeing < 0.8 , airmass < 1.2 and clear conditions.
  The targets are in crowded Bulge fields and therefore the better
  the seeing & strehl the better we can resolve the microlensing 
  event from the background.

Time-Critical Aspects

• The earlier the observation are done the better the science return will
   be for us.
  Since the objects are still slightly magnified, observing done before
  end of August would allow us to better disentangle between the lens and the source.
  
  Please note that
  OB-Template MOA-197 has priority over the other observation.
  
  No star within 2 arcmin of the target is brighter than V=11 (field
  MOA-197), respectively V=10 (MOA-192).
  
  Note also that the faint MOA-192 event (K >~18)  is not visible in the
  finding chart, but the cross hair marks it presumed position.
