Estimated Total Execution Time (hours, including overheads)

• 0.96 ... including the telluric observation

General Description

• Monitoring program of a fading object. One OB per SV slot should be executed.
   
  Only the OBs for the first epoch have been currently submitted (Target+Telluric)
  
  Simple auto nod on slit observation (just one cycle) of a candidate red-nova. 
  
  The current magnitude of the object is not known but it was V~18 on April 2009.
   
  The line intensity is unknown too. Please check for possible saturation of the VIS
   or UVB detector and decrease the UVB or VIS exptime of the second exposure if necessary.
   Note that the Halpha line is in 2 orders (25 and 24), so its saturation in JUST
   ONE of the two orders (likely 25) is not critical. It should not saturate in both,
   though! (in which case, please decrease the VIS exptime)
  
  
  A B3V telluric OB has been prepared. Please check the special calib and execution
   requirement sections. The telluric should be changed for another hot main sequence
   featureless star in the case the target is not observed at the beginning of the
   night.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• none.

Time-Critical Aspects

• none

Special Execution Requirements

• The target is visible at the beginning of the night. 
  The provided telluric is at optimal distance and airmass if the program is started
   within ~3 hr since the beginnng of the night. 
  On the contrary the telluric should be changed. 
  Please look for a hot MAIN SEQUENCE star (B0-B5).

Special Calibration Information

• Telluric (B3V V=7.67mag) OB provided. 
  Should the actual target be changed any other hot main sequence star would be OK.
   
  Just change the coordinates in the OB as needed.  
  
  We assume that the specphot observation is taken during the night twilight and it
   will be sufficient to our science goal.
