TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2864 SUBJECT: GRB 041217: PROMPT Observations DATE: 04/12/19 02:02:03 GMT FROM: Melissa Nysewander at UNC,Chapel Hill Matt Bayliss, Melissa Nysewander, Andrew Foster, Dan Reichart, and Jane Moran report on behalf of the U. North Carolina team of the FUN GRB Collaboration: We imaged an 11.7 arcmin x 11.7 arcmin field near the center of the localization of GRB 041217 (Palmer et al., GCN 2853) for 96 x 60 sec in Rc beginning 22.7 hours after the burst with PROMPT Telescope 5 at CTIO. Visual comparison to POSS2-Red reveals no obvious transients, however our image goes deeper. Calibration to 6 USNO-A2.0 stars yields a 3-sigma limiting magnitude of Rc = 21.5 at a mean time of 23.8 hours after the burst for this region. Only the first candidate of Berger & Gonzalez (GCN 2859) would lie in our field, but we find nothing at this location. Our image can be found at: http://www.physics.unc.edu/~mnysewan/grb041217.html PROMPT is very early into construction and commissioning. Enclosure construction began in September 2004: http://www.physics.unc.edu/~evans/promptcam/promptcam.html Construction and commissioning of the first two telescopes began only two and a half days prior to this burst. All six telescopes will be completed and upgraded to 0.41m Ritchey-Chretien telescopes by mid-2005. For more information on PROMPT: http://www.physics.unc.edu/~reichart/prompt.html
