Dae-Sik Moon, S. Bradley Cenko (Caltech), and Joe Adams (Cornell) report
on behalf of the Caltech-NRAO-Carnegie GRB Collaboration:
"We have imaged the field of GRB041219 with the Wide Field Infrared
Camera (WIRC) on the Palomar 200-inch Hale Telescope. We can confirm the
presence of a fading source at the position reported by Blake and Bloom
(GCN 2870). Our K_s magnitudes (with reference to the 2MASS catalog) are
as follows:
UT (Dec 19) t_burst K_s Magnitude
