TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2865 SUBJECT: GRB 041219: PAIRITEL IR Observations, < 3 minutes after trigger DATE: 04/12/19 02:35:52 GMT FROM: Josh Bloom at Harvard/CFA GRB 041219: PAIRITEL IR Observations, < 3 minutes after trigger J. S. Bloom (CfA/UCB) reports on behalf of a larger group: "Responding to the IBAS Alert #2073, we imaged the field of the (possible) GRB 041219 starting at 19 Dec 2004 01h49m18 UT, about 2.8 minutes after the GRB (imaging is on-going). A quick comparison with the 2MASS Quicklook J-band images reveals no obvious new source. The imaging depth is deeper than 2MASS. A more detailed analysis is on-going." This message may be cited.
