Crain, and A. Foster report on behalf of the UNC team of the FUN GRB
Collaboration.
Under the control of Skynet, PROMPT Temporary Telescope 3 automatically
observed the localization of GRB 051109 (Tagliaferri et al., GCN 4213)
beginning 1.7 min after the burst in repeating blocks of B and V.
PROMPT Temporary Telescope 5 joined PROMPT-3 15.6 min after the burst in
repeating blocks Rc and Ic. These observations were carried out in synch
with PROMPT-3's observations.
We detect the afterglow (Rykoff et al., GCN 4211) in single V, Rc, and Ic
exposures and measure its brightness to be V ~ 16.6 mag at 3.3 min after
the burst.
PROMPT is still being built and commissioned.
