J. Haislip, C. MacLeod, M. Nysewander, A. Foster, J. A. Crain, D. =
Reichart,
M. Bayliss, J. Kirschbrown, and C. Mack report on behalf of the UNC team =
of
the FUN GRB Collaboration:

We observed the BAT localization of GRB 050525a (Band et al., GCN 3466)
with PROMPT-5 beginning 5.3 hours after the burst.  We detect the =
afterglow
(Rykoff et al., GCN 3465) in VRcIc across multiple epochs.

Using the field calibration of Nysewander et al. (GCN 3566), we find =
that
Rc =3D 19.84 +/- 0.11 mag at a mean time of 8.1 hours after the burst.

PROMPT is still being built and commissioned.
