Super-Lotis And Lotis For Hete2 Grb Triggers

LOTIS (Livermore Optical Transient Imaging System) and Super-LOTIS are automatic telescope systems that search for prompt optical emission from gamma-ray bursts (GRBs). Both systems are capable of responding to the Gamma-ray burst Coordinate Network (GCN) triggers within seconds. These systems have been monitoring the GCN real-time data for automatic HETE2 GRB triggers since HETE2's launch. In this paper, we present the systems' capability and current status. We also present the result of the GRB010921 afterglow detection that was localized by HETE2 and the IPN.
