Price (IfA/Hawaii) report\non behalf of the Caltech-NRAO GRB Collaboration:\n\n\"We have reobserved the HETE-2 WXM localization region for XRF030824\nwith the 200-inch Hale Telescope and Large-Format Camera on\nMt. Palomar.  Our dithered 4x300s images cover 95% of the\n22.4'-diameter error circle at a mean epoch of August 26.42 UT, 1.72\ndays after the event.  PSF-matched image subtraction of our\nfirst-epoch image (mean epoch Aug 25.25; Fox & Hunt, GCN 2364) does\nnot reveal any bright, stationary, variable objects within the part of\nthe WXM localization region covered by our images.  The limiting\nmagnitude of the individual images is approximately R~24.5.  Within\nthis region we set a lower limit of R>22.5 on the magnitude of any\nstrongly variable optical counterpart to XRF030824 at either epoch.\nThis is a conservative lower limit, which we consider appropriate\ngiven the size of the region.\n\nSeparately, we note the presence of a slow-moving (15\" per hour,\nPA=-73 deg) object within the error circle in our Aug 25.25 image,\nnear RA 00:05:36.69, Dec +19:59:56.9 (J2000), with an approximate\nR-band magnitude of 19.9.  \n\nThe nearest star to the location of the object reported by Moran et\nal. (GCN 2363) is constant in brightness in our two images.  We find\nno variable objects in the near vicinity; however, the location is\nonly 15\" from the borders of our imaged region.\n\nObservers interested in making their own investigation of these data,\nor comparing with other datasets, should contact Fox by email to\narrange for data transfer.\"",
