H. Terada and M. Akiyama (Subaru Telescope, NAOJ) report:

"We observed the field of the optical afterglow candidate (Fox and
Moon, GCN 2734) of GRB 040924 (=H3564, Fenimore et al., GCN 2735) in
the K'-band with IRCS on the 8.2m Subaru Telescope at 14:12-14:23 UT
on September 24 (2.4 hours after the burst).

At the position of the OT candidate, we detected a source 
with magnitude K'= 17.5."
