General Description

Optical spectroscopy of the optical counterpart of the bright X-ray source
 in the circinus galaxy. 
We have identified a faint source in FORS V and I band imaging and want low resolution
 spectra
of the source to determine its nature. Acquisition of the target should be done
 as follows:

In order to be sure of locating the faint source in this crowded inner galaxy region,
 we would
like the slit aligned with two bright sources which will be easy to identify. The
 target falls
between these two, exactly along their alignment. We will use a 2" slit to be sure
 of getting all
the flux in the slit. We have estimated the PA of the slit to be 55 degrees East
 of North and 
have specified that in the OBs. The through slit image should be used to identify
 the two 
acquisition stars (marked on the zoom finding chart) and the slit sligned with these.
 
We used this strategy in Period 74 to observe the target and it was successful -
 although
our OBs were not completed.
