TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2855 SUBJECT: GRB041217: P60 Optical Observations DATE: 04/12/18 14:04:30 GMT FROM: S. Bradley Cenko at Caltech S. Bradley Cenko reports on behalf of the Caltech-NRAO-Carnegie GRB Collaboration: "We have imaged the entire 12-arcmin radius error circle of the Swift GRB 041217 with the robotic Palomar 60-inch telescope. Observations consisted of 25 x 120-second exposures in the Gunn g and Kron I filters. High winds led to extremely poor seeing conditions (~ 3-arcsec average). To a limiting magnitude of I~19.5 we detect no new objects by reference to the Digitized Sky Survey (second epoch). Continued analysis and further observations are planned."
