General Description

This is a proposal for the search for 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 in 4 imaging runs.
The first 2 have already been executed. For run C we would like to obtain L band
 imaging, preferably before the 25th June (OB 325459).

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 27"x27" FOV has K~12.8 mag.

Waiver Requests

Waiver for OB lengths of more than 1h have been approved by Christoph
 Dumas.
We are requesting to observe with L band for run C, in order to get colour information
 of the very extincted field.

Critical Observing Condition Constraints

```
N/A
```

Time-Critical Aspects

The first epoch (run A) should be executed as soon as possible. Preferably
 the night of June 3/4, making them quasi simultaneous to Chandra X-ray observations.
Run B should be executed optimally on June 5/6 or 6/7 when observations from CXO/RXTE
 will be performed.
Run C should be executed preferably before June 25/26.
The preferred execution dates of run D will be defined according to the results
 of the previous runs A, B and C.
If some run cannot be executed on the precise date please do so as soon as possible.
