(TLS �Tautenburg)\nreport on behalf of a larger collaboration:\n\nWe observed the BAT �error circle of the Swift trigger 315630 (Pagani et al.,\nGCN 7912) with the TLS 1.34m Schmidt telescope under moderate seeing \nconditions (seeing >2 arcsec). We obtained in total 12 x 300 sec images in R \nband starting at 00:16 UT �and finishing at 01:19 UT. We did not find any new \nsource in the stacked image down to the 3-sigma limiting magnitude of 22.5 \nmag calibrated on USNO-B1 field stars.\n\nThis message can be cited.",
