Ludwig, Thuringer Landessternwarte Tautenburg\n\nreport:\n\n\nThe field of GRB 030131 was imaged in the R band with the Tautenburg\nSchmidt telescope equipped with the prime focus CCD camera on Feb 4,\n1:35 - 5:22 UT. The field of view is about 40 x 40 arcmin. Altogether\n45 frames were taken (2 min exposure time each). The limiting magnitude of\nthe combinded image is about R=22.5 +/- 0.5. The GRB field is very rich in\ngalaxies. Exactly at the position of the potential afterglow\ncandidate reported by Oksanen et al. (GCN 1849) we do not detect any\nsource (R>~22.5). Several sources with R>~21 are visible within ~5 arcsec\nof the reported OT coordinates.\n\nThis message may be cited.",
