LOTIS (Livermore Optical Transient Imaging System) is a gamma-ray burst optical counterpart search experiment located near Lawrence Livermore National Laboratory in California. The system is linked to the GCN (GRB Coordinates Network) real-time coordinate distribution network and can respond to a burst trigger in 6{endash}15 seconds. LOTIS has a total field-of-view of 17.4{degree}{times}17.4{degree} with a completeness sensitivity of m{sub v}{approximately}11 for a 10 second integration time. Since operations began in October 1996, LOTIS has responded to over 30 GCN/BATSE GRB triggers. Seven of these triggers are considered {ital good} events subject to the criteria of clear weather conditions, {lt}60 s response time, and {gt}50{percent} coverage of the final BATSE 3{sigma} error circle. We discuss results from the first year of LOTIS operations with an emphasis on the observations and analysis of GRB971006 (BATSE trigger 6414). {copyright} {ital 1998 American Institute of Physics.}
