TITLE: GCN GRB OBSERVATION REPORT NUMBER: 3608 SUBJECT: GRB 050714A: ROTSE-III Optical Limits DATE: 05/07/14 01:31:23 GMT FROM: Brad Schaefer at LSU B. Schaefer (Louisiana State), S.A. Yost (U Mich), H. Swan (U Mich), E.S. Rykoff (U Mich), report on behalf of the ROTSE collaboration: ROTSE-IIId, located at the Turkish National Observatory at Bakirlitepe, Turkey, responded to GRB 050714A (Integral trigger 2598), producing images beginning 9.1 s after the GCN notice time. An automated response took the first image at 00:06:33.1 UT, 27.9 s after the burst, under excellent conditions. We took 10 5-sec, 10 20-sec and 60 60-sec eposures. These unfiltered images are calibrated relative to USNO A2.0 (R). Comparison to the DSS (second epoch) reveals no new sources within the 3-sigma error circle, for both single images and coadding into sets of 10. Individual images have limiting magnitudes ranging from 16.5-17.9; we set the following specific limits. start UT end UT t_exp(s) mlim t_start-tGRB(s) Coadd? -------------------------------------------------------------------- 00:06:33.1 0:06:38.1 5 16.6 27.9 N 00:06:33.1 0:08:55.1 142 18.2 27.9 Y
