FORS1 imaging with occulting bars of optical counterpart of 
eclipsing X-ray binary.  A waiver has been granted to allow 
a 2-hour OB duration, under the usual condition that if 
conditions degrade beyond those specified after 1 hour, the 
observation will not be repeated.  One target, one (two hr 
long) OB.  Since the purpose of this programme is to look 
for time-variability, the P.I. wants the OB for this run 
to be executed on a different night than those for the 
associated run 073.D-0045(B).
