General Description

• Supporting spectroscopic monitoring for the interferometric AMBER/VLTI
   study of the 
  circumstellar disk of the Be star delta Sco. Using the self-consistent disk model,
  we would like to determine its main geometrical and  physical parameters.
  The Feros spectroscopic observations to be taken before during and after the AMBER
   run
  on July 14/15 and 15/16 will provide information about the disk evolution and more
   
  constrains for the modeling.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• The OB can be done almost under any conditions. Even the seeing and air
   mass slightly higher than 2.0 and thin-thick cirrus  are acceptable if the integration
   time is increased 
  appropriately.

Time-Critical Aspects

• The observations are time critical. Of the 9 identical OB, 4 must be executed
   during
  the interferometric observations, 3 before and 1 after them. In order to achieve
   the 
  maximum coordination with the interferometric observations and needed info on the
   evolution of
  the circumstellar disk on the appropriate time scale, the following schedule should
   be 
  followed
  OB 1: June 13-18
  OB 2: June 28 - July 2
  OB 3: July 6-8
  OB 4: July 14, beginning of the night
  OB 5: July 14, end of the night
  OB 6: July 15, beginning of the night
  OB 7: July 15, end of the night
  OB 8: July 21-23
