The Chandra ToO observation has been approved for GRB 111117A
(Mangano et al., GCN Circ. 12559; Sakamoto et al., GCN Circ. 12561).
The observation has been tentatively scheduled on November 20 12:48 UT
for 20 ksec.
This is the approved ToO program in AO-13 to identify a Swift short GRB
afterglow in X-rays by a sub-arcsecond position from Chandra
(PI: Sakamoto, #501616). The main goal is to identify the host galaxy
of GRB 111117A by the sub-arcsecond X-ray position which is very likely
to be able to obtain from the Chandra observation. Therefore, we strongly
encourage deep optical observations of the field.
