Jakobsen (University of Copenhagen) report:\n\nWe have obtained V, R and I-band images of the error box of GRB 030329 \n(Peterson & Price 2003, GCN 1985) using the Danish 0.4-m Brorfelde Schmidt \ntelescope. We compared our images with the Digitized Sky Survey and detected\nthe optical afterglow of GRB 030329 at:\n\nRA: 10:44:50.03   Dec: +21:31:18.1   +- 0.5 arcsec     (J2000)\n\nThe following table contains our data for this object:\n\n\nDate\tTime(UT)   Exposure time(s)\tBand\tMagnitude   \n--------------------------------------------------------------\nMar 29   20:21 \t   \t1080 \t\tR\t14.54+-0.01\t\t\nMar 29   20:58 \t    \t 600 \t\tR\t14.57+-0.01\t\t\nMar 30   19:16 \t    \t 360 \t\tR\t16.35+-0.05\t\t\nMar 30   19:30 \t    \t 540 \t\tR\t16.35+-0.04\t\t\nMar 31   21:18\t    \t 540 \t\tR\t16.80+-0.04\t\nApr 7    21:00 \t    \t 270 \t\tR\t19.24+-0.29\t\t\nApr 7    21:08 \t    \t 540 \t\tR\t19.20+-0.18\t\t\nApr 7    21:45 \t   \t1620 \t\tR\t18.92+-0.13\t\t\nApr 7    22:26\t   \t1800 \t\tI\t18.82+-0.14\t\t\nApr 7    23:06\t   \t1800 \t\tV\t19.09+-0.14\t\t\n--------------------------------------------------------------\nTime is measured from start of observation.\n\nThe photometry of the afterglow is with respect to 11 stars from \nHenden (GCN 2023). The quoted errors in the I and V bands may be \nunderestimated. We fitted a single power law to our data in the \nR-band. We found a power law slope of 1.31 +- 0.04.\n\nThe combined images are made available at:\nhttp://www.fys.ku.dk/~kindt/bachelor/\n\nThanks to J. Hjorth, K. Augustesen, and H. Pedersen.",
