J. Moran, M. Nysewander, D. Reichart, P. Yim, C. Zdanowicz, and J. Reichart
report on behalf of the UNC GRB team of the FUN GRB collaboration:
We are currently observing the error region of GRB 030824 (HETE 2821) with
the 0.6-meter Morehead Observatory telescope in R band through haze and
fog. We detect a source that does not appear in DSS/POSS-II or 2MASS, at:
RA: 00:04:36
DEC: 19:48:57
This source is near our detection limit, but is clearly visible in most of
our individual frames, which now span many hours.
We tentatively estimate its magnitude to be R ~ 17. We cannot rule out the
possibility of a variable/flare star.
A more detailed analysis will follow.

M.C. Nysewander, J.C. Clemens, J.A. Moran and D.E. Reichart (University of
North Carolina) report:
Upon further inspection of the images of the candidate reported by Moran et
al., GCN 2363, we find that the transient was the product of faulty
hardware. Our new camera had not been fully tested by the time of the
burst alert, and below spec CTE problems seemed to have caused the
fading/variable source apparent in the images. We apologize for any
confusion.
