Estimated Total Execution Time (hours, including overheads)

• 5

General Description

• This proposal monitors two planetary transits (one for each observing
   run); therefore, timing constrains are critical. The observation of each transit
   will last 5 consecutive hours, therefore we have prepared 5 one hour OBs in order
   to cover each transit. We have selected the I filter (instead of V) because the
   second transit will run into the twilight and therefore observations will be less
   affected by it.
  There is a very bright star near the target object that it is important to leave
   outside the frame even if this means that the target object will not be centered
   in the field.
  
  There are 3 possible transits events and we need to observe two of them (one for
   each observing run), their timings are indicated in the OBs. To observe the two
   earliest events would be the best given that they are farther from the twilight,
   the third should only be observed in case of technical or weather problem in one
   of the first two.
  
  The finding chart is an image taken in the R filter. Its size is approximately 2.5
   arcmin.

Waiver Requests

• A Waiver was requested to perform the 5 OBs continuously and have a nominal
   total time of 5:24:25, which translates in less than 5 hours after considering the
   time saved by skipping the acquisition between successive OB.

Critical Observing Condition Constraints

• Thin cirrus would be acceptable and seeing better than 1.5 arcsec

Time-Critical Aspects

• This sequence of 5 OBs should cover the full transit. The OBs belonging
   
  to this run should be executed after completing the OBs of the run A and 
  the possible starting time/date for the observation are:
     start                   emd
  2006-12-23T04:10:00   2006-12-23T09:10:00
  2006-12-27T04:40:00   2006-12-27T09:40:00
  Please keep observing as long as possible towards the sunrise.
