Special Remarks:
Rapidly setting source. Observe as soon as possible, but definitely before the end of December.


 
Simple imaging of one Gammy Ray Burst field in four filters: NB1.19, 
NB1.71, Js and H.  The NB1.71 observations is split into two OBs, so 
there are five OBs in total.  Two OBs are slightly longer than 1 hour 
(66 min.), but they should still be scheduleable.  Since the field 
of this Gamma Ray Burst is rapidly setting, the ISAAC service run 
from Dec. 15-19 is essentially the only opportunity to complete 
this program.  Since the source only has airmass < 3 for the first 
few hours of the nights during this ISAAC service mode block, the 
program will have to be executed over several nights.  No useable 
finding chart was received for this observing program.  Since a 
fast execution is crucial to the success of this program, a blind 
pointing to the coordinates listed in this OB will have to be done.
