GCN Circular 10101
A. Moskvitin, T. Fatkhullin (SAO-RAS Niznijh Arkhyz, Russia), on behalf of a larger colaboration, report: We observed the field of the GRB 091024 afterglow (Marshall et al., GCN 10062) with the Zeiss-1000 telescope of SAO RAS, Russia. The observations were carried out starting from October, 24.651 (15:37 UT) till October, 24.976 (23:26 UT). In total 29 * 300 sec. exposures in the Rc-band and 29 * 300 sec. exposures in the V-band were obtained. During the observations we detected a faint fading object at the position reported by Mundell et al. (GCN 10063) as well as a small extended object with R~20.8 in ~2 arcseconds to the North-West from the afterglow (see also Kann and Laux GCN 10077). The brightness of the OT in the first stacked R-band images (the mean epoch is 16:52 UT) is R = 20.7 +/- 0.2 (we admit some contribution in flux from the extended object). It is not clear at this stage if the extended object is a host galaxy or a foreground galaxy responsible for the absorption line system reported by Cucchiara et al. (GCN 10065) and Cenko et al. (GCN 10093). The data analysis is in progress. Photometry was carried out using nearby USNO B1.0 stars (R2 magnitudes). This message may be cited.
