Estimated Total Execution Time (hours, including overheads)

• 7 hours

General Description

• This program aimed at obtaining ~5 hours of integration around Halpha
   and ~1 hour around 860nm of the runaway black-hole GRO J1655-40, currently in quiescence,
   with the goal of performing an abundance analysis. All OB are exactly 1 hour long.
   There are 5 OBs for the Halpha region, called DDT_GRO_J1655-40_REDX, where X=1..5,
   and one DDT_GRO_J1655-40_VERY_RED for the 860nm region. 
  
  The goal of this program is to obtain a spectrum as good as possible, but as soon
   as possible too. The target is observable mostly at the end of the night only. We
   request that airmass must be smaller or equal to 2. If by any chance two OBs of
   the target are executed in a row, or the acquisition time appears to be much less
   than 10 minutes, we would like the support astronomer to increase the exposure time
   to compensate for it. Thanks!
  
  Thanks also to USD we have been authorized to submit 5+1 (6) corresponding OBs for
   a standard star to be observed (total exp. time has been put to 7h). The names are
   DDT_HD156098_REDX, where X=1..5 and one DDT_HD156098_VERY_RED. When an observation
   of GRO J1655-40 is performed, the corresponding OB of the standard star must also
   be preformed (i.e. the same night). The observation of the standard star can be
   done during twilight.
  
  The old OB "DDT_HD156098_RED" is dummy and can be deleted.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• No rain.

Time-Critical Aspects

• Given the observability of the object, observations should not be carried
   out before January 30. 
  Since it is a potential target for regular proposal in P78, program must be completed
   by March 15, 2006.

Special Execution Requirements

• None.

Special Calibration Information

• We would like the standard star HD156098 to be observed once.
