C. MacLeod, M. Nysewander report on behalf of the UNC team of the FUN GRB
Collaboration:
We have observed the position of the GRB 050820a afterglow reported by Fox
et al. (GCN 3829). We detect the afterglow in RcIc:
Mean Time Integration Filter Magnitude Telescope
Since GRB Time
2.2 hr 39 x 40 sec Ic 17.40 +/- .08 PROMPT-3
2.2 hr 22 x 30 sec Rc 17.64 +/- .09 PROMPT-5
21.5 hr 136 x 40 sec Ic 18.42 +/- .11 PROMPT-3
21.7 hr 179 x 30 sec Rc 20.06 +/- .31 PROMPT-5
Rc and Ic calibrations were made relative to 7 calibration stars posted by
Henden (GCN 3845).
PROMPT is still being built and commissioned.
