Castro Ceron, ROA (San Fernando) on behalf of\nthe large Spanish-Czech BOOTES team, report:\n\nWe have observed the entire error box of GRB 000323\n(cf. Hurley et al., GCN#616), using the 0.3-m BOOTES-1\ntelescope and the USNOFS 1.0-m telescope.  The BOOTES-1\ndata is unfiltered, and covers about 90 percent of\nthe entire error box except for the extreme northern\nand southern corners.  The USNO Cousins R-band data is a\nnorth/south mosaic that covers about 60 percent of\nthe error box, missing the east and west corners.\nThe UT exposure dates, length, and limiting magnitudes are:\n\nBOOTES-1  2000 March 25.00  1200seconds  R=19.5\nUSNO      2000 March 25.42   600seconds  R=21.5\nUSNO      2000 March 26.31  1200seconds  R=22.2\n\n\nThe BOOTES-1 frame does not go as deep as the POSS-II red\nplate, but no new object is apparent from comparing the\nCCD data with POSS-II.  The USNO datasets go somewhat\ndeeper than POSS-II, but no variable object is detected\nbrighter than R=21.5.\n\nA BVRI single-night calibration of the central part\nof the error box, taken on a photometric night in conjunction\nwith a large number of Landolt standards, can be found at\nftp://ftp.nofs.navy.mil/pub/outgoing/aah/grb/grb000323.dat",
