General Description

This is a proposal for the search of a near infrared counterpart of the
 soft gamma-ray repeater SGR 1627-41, which is in outburst since the 28th May after
 10 years.
The observations consist of imaging in four epochs.
The first 3 have been already obtained.
In the last visit we will do imaging in Br-gamma narrow band filter and K-band.

The magnitude of the reference star was V~14.5 in the catalogue, but in previous
 runs it was fainter than expected. We have increased the magnitude to V~16.5 as
 suggested by USD. Anyhow we keep the folloing comment from Dieter: 
IMPORTANT NOTE: The AO acquisition is a bit difficult (as the NGS R1 might be fainter
 than expected at optical wavelengths). Once the NGS R1 has been centered in the
 WFS Field Selector Box in the CONICA RTD, it might not be visible in the WFS sub-apertures
 in the NAOS RTD. In this case we suggest to change the VIS WFS mode to a suitable
 mode that uses 4x4 pixels per WFS sub-aperture and binning of 2. During the first
 epoch observation we were able to successfully perform the AO acquisition on NGS
 R1 by using the VIS WFS mode 2-5. 

The brightest star within the NACO 54"x54" FOV has K~11 mag.

Waiver Requests

Waiver for OB lengths of more than 1h have been approved by Christoph
