General Description

The goal of this observing run is to obtain SINFONI observations of the
 brightest Lyman break galaxy in the sky, the 8 o'clock arc.
The system is gravitationally lensed by a foreground elliptical galaxy and is split
 in four but the three brightest images are the main focus of the observation although
 the orientation of the instrument has been chosen to also include the fourth image
 just south of the elliptical. 

As can be seen on the finding chart the images are located along an arc just north
 of the elliptical. The third finding chart shows a rotated view which should correspond
 to the view on the detector. The center is indicated by the green cross and is the
 Target in the OBs as well as having its RA & DEC on the image. The position
 of the elliptical is also indicated along with its photometry as derived from 2MASS
 images (quite noisy). 

I do not have sufficient continuum NIR data for the arc to state whether it should
 be visible in the acquistion images or not but I chose a slightly longer than necessary
 DIT for the elliptical in the hope that it would appear.

Critical Observing Condition Constraints

To get a good AO correction we need good seeing conditions. Due to the
 additional constraints on the LGS use we have decided to relax the requirement from
 our proposal (0.6") to 0.8" for J where the Strehl would anyway be rather poor.
 We still keep our 0.6" constraint for H & K to be able to get high resolution
 emission line maps.

Time-Critical Aspects

Special Execution Requirements

We would give preference to the H-band, J-band and K-band observations
 
in that order.
