TITLE: GCN CIRCULAR NUMBER: 10249 SUBJECT: GRB 091127: Skynet/PROMPT Observations of Possible Host Galaxy DATE: 09/12/05 19:43:23 GMT FROM: Josh Haislip at U.North Carolina J. Haislip, D. Reichart, K. Ivarsen, A. LaCluyze, R. Egger, A. Foster, J. Moore, A. Oza, M. Schubel, J. Styblova, A. Trotter, J. A. Crain, and M. Nysewander report: Skynet continued to observe the afterglow (Smith et al., GCN 10192) of GRB 091127 (Troja et al., GCN 10191) with four of the 16" PROMPT telescopes at CTIO in BVRI (Haislip et al., GCNs 10107, 10230) Between 4.1 and 7.3 days after the trigger, the light curve is consistent with constant emission, which suggests that we are observing the host galaxy. If so, we measure its brightness to be: I = 21.19 +/- 0.14 (statistical) +/- 0.39 (systematic; calibrated to 65 USNO B1 stars). R = 21.27 +/- 0.13 (statistical) +/- 0.37 (systematic; calibrated to 115 USNO B1 stars). V > 21.9 (3 sigma; calibrated to 14 NOMAD stars). B > 21.2 (3 sigma; calibrated to 65 USNO B1 stars).
