TITLE: GCN CIRCULAR NUMBER: 7917 SUBJECT: TLS I-Band Observation of GRB 080701A DATE: 08/07/01 22:28:54 GMT FROM: Andrea Rossi at TLS Tautenburg Rossi, A. (TLS Tautenburg), Gonsalves, E. (U. Dartmouth), Schulze, S. (TLS Tautenburg), Klose, S. (TLS Tautenburg), Filgas, R. (TLS Tautenburg), and Ludwig, F. (TLS Tautenburg) report on behalf of a larger collaboration: We observed the X-ray error circle of the Swift GRB 080701A (Evans, P. A. et al., GCN 7914; Stroh, M. C. et al., GCN 7910) with the TLS 1.34m Schmidt telescope under good observing conditions (seeing is about 1-2 arcsec and very good visibility). We obtained in total 10 x 150 sec images starting at 21:02 UT and 5 x 300 sec images starting at 21:40 UT in the I band. We did not find any new source in the stacked image down to the 3-sigma limiting magnitude of 21.7 mag calibrated on USNO-B1 field. This message can be cited.
