FORS2 imaging of the rapidly evolving Helium shell flash star V4334 Sgr 
(Sakurai's Object).  Goal of this run is to check for time-variability 
compared to identical imaging obtained in run A of this program, so 
it is important that these images be obtained approximately 2 months 
after run A, which was completed on April 29/30.  Two imaging OBs, both 
on the same target, but with a different set of filters.  The first OB 
(#135101) contains a long exposure in the H_Alpha+83 filter, and short 
exposures in UBVRI.  The second OB (#135100) only contains one short 
and one long exposure in the H_Alpha/2500+60 filter.  For the first 
(multi-filter) OB, the P.I. has been informed that the constraint set 
only applies to the long exposure in the H_Alpha+83 filter.  Apart from 
reasonably good seeing conditions (< 0.8"), no stringent constraints 
on observing conditions.
