TITLE: GCN GRB OBSERVATION REPORT NUMBER: 3228 SUBJECT: GRB 050408: PROMPT VRcIc Observations DATE: 05/04/10 23:35:56 GMT FROM: Matt Bayliss at UNC,Chapel Hill M. Bayliss, M. Nysewander, J. Haislip, J. A. Crain, A. Foster, J. Kirschbrown, C. MacLeod, and D. Reichart report on behalf of the UNC team of the FUN GRB Collaboration: We have observed the position of the GRB 050408 afterglow reported by de Ugarte Postigo et al. (GCN #3192) with three telescopes of the PROMPT robotic array, one in each of VRcIc. In one epoch of V-band observations, 122 x 60s exposures centered on April 9, 02:06:44 UT (t + 9.7 hours), we have a 3 sigma detection of the afterglow at V ~ 21.4. In a second epoch of 137 x 60s eposures centered at 05:37:31 UT (t + 13.2 hours) we do not detect the afterglow down to a limiting magnitude of V = 21.7 (2 sigma). V filter calibrations were made relative to 6 Nomad stars. PROMPT is still being built and commissioned.
