Quimby (U Texas), \nreport on behalf of the ROTSE collaboration:\n\nA fast fading optical transient has been discovered inside the error \ncircle for GRB 051111A (Swift trigger 163438, Sakamoto et al, GCN 4248) \nby the ROTSE-IIIb telescope, located at McDonald Observatory (see \nRujopakarn et al, GCN 4247). The initial response was during the BAT \nemission, when the transient was at 13.0 mag (unfiltered, relative to \nUSNO A2.0). The transient faded as a simple power law with decay index ~ \n-0.9. At UT 06:41:57 (t+2500s), the transient was at 17.4 mag.\n\nContinuing observations are in progress.",
