General Description

This observation aims at studying the optical counterpart of a triple
 X-ray source P8 in the galaxy NGC 7793. The X-ray source is well aligned with a
 supernova remnant candidate S26 and the central X-ray source appears coincident
 with a blue ~23 mag star.
We propose here to carry spectroscopic observations to study the bubble and the
 stellar counterpart.
The 4 spectroscopic observations should be carried out randomly. The standard configuration
 will be LSS Grism 300V+10 with no filter and slit width of 1.0\", slit orientation
 along the triple X-ray source (rotator = +32.1deg).
One extra spectrum will use LSS Grism 600V+94 with the GG375+30 filter and slit
 width of 0.7" and slit orientation as above.
The finding chart is showing the target for which there is the need to use a blind
 offset.

As we got a special authorization to change the moon constraint, we have now 1.5
 guaranteed hour that we would like to use for one spectrum with grism 300V and one
 spectrum with grism 600V (OBs 0 and 3). The two others OB correspond to the 1.5
 hour on hold.
