Estimated Total Execution Time (hours, including overheads)

```
4:04:28
```

General Description

The purpose of this program is to monitor the proper motions of the stars
 in the Galactic Center. Execution should be in April, the Galactic Center is visible
 in the morning hours.

Please note that the reference star R2 should be centered on pixel 430/570 during
 acquisition.

If in the first frame of the sequence you notice reflections as shown in the file
 'reflection.jpg' (part of the set of findind charts) please change
the centering scheme and move to another y position, e.g. try 590 or 530 instead
 of 570. (550 already is known to produce the reflections.)
The reason for the reflection is that the bright AO guides star (labelled R1) is
 falling on the edge of the detector mount.

Time-Critical Aspects

Execution should be in April, the Galactic Center is visible in the morning
 hours.

Special Execution Requirements

The attached finding chart shows a mosaic of the Galactic Center region
 as obtained with NACO in previous runs.

Please note that the reference star R2 should be centered on pixel 430/550 during
 acquisition

If there are Finding Charts attached to your OBs, is the field-of-view of at least one of these charts 2' x 2' (with clearly labelled field orientation) ?

Have you clearly marked and labelled your wavefront reference objects R1, R2, R3, ... (as specified in the NAOS Preparation Software) on your Finding Charts ?

Have you specified the magnitude of the brightest object in the field-of-view for each OB ?

Are there objects in any of your fields (including standard stars) which are brighter than the limits specified in the User Manual and on NACO web Pages ?

If the previous answer is yes, have you given a list of OBs and a justification for the brightness limit violation in the general description field ?
