General Description

We intend to measure the linear NIR polarimetry of a point source, GRO
 J1655-40, on 5 different dates from 29/09/2005 until the source is below the horizon
 and unobservable (~end of October).
- Note that the target will appear much brighter than in the attached finding chart
 because the source is in outburst.
- We wish for the target and standards to be placed at pixel (x,y)=(512,540), to
 ensure they do not move behind the mask after the field is rotated.
- The target is declining from an outburst, and should decrease by ~ 0.5-2 magnitudes
 in the next month.  After ~ the end of October the source is below the horizon from
 the VLT and unobservable so it is essential that the 11 OBs are completed before
 this date.
The magnitude of the brightest star in the FOV of all OBs is J~12.

Critical Observing Condition Constraints

Sky transparency: thin cloud.  No further constraints.

Time-Critical Aspects

This is an approved DDT.  After ~ the end of October the source is below
 the horizon from the VLT and unobservable so it is essential that the 11 OBs are
 completed before this date.

Special Execution Requirements

Special Calibration Information

We like to have one of the standard stars observed after each
science OB. I suggest the one remaining standard star OB
to be added at the end of one of the 
current "target+standard" OBs -like this:
 
1)  Target + standard1
2)  Target + standard1 + standard2
3)  Target + standard1
4)  Target + standard2
5)  Target + standard2

where "Target", "standard1" and "standard2" represent
the OBs of the target, the first standard star and the
second standard star, respectively.
