GCN Circular 2884
Dae-Sik Moon, S. Bradley Cenko (Caltech) and Joe Adams (Cornell) report on behalf of the Caltech-NRAO-Carnegie GRB Collaboration: "We have continued to image the NIR afterglow of GRB041219 (Blake and Bloom, GCN 2870) with the Wide Field Infrared Camera (WIRC) on the Palomar 200-inch Hale Telescope. Our latest observations in the K_s band, taken at a mean time of 01:58:00 UT (1.01 days after the burst), put the object at a magnitude of 16.5 (with reference to the 2MASS catalog). This is a significantly shallower decay than we reported for the early afterglow (GCN 2876). Further observations are planned."
