Even though many GRBs are now identified with late time afterglows, very few measurements are available on their prompt properties. Unlike delayed afterglows, early-time follow-up measurements will contain information about the GRB progenitors. These measurements are possible via automatic observations triggered by the GRB satellites. We have been operating automatic and rapidly slewing telescope systems, LOTIS (0.11 m aperture; 4 simultaneous astronomical filters) and Super-LOTIS (0.6 m aperture), to detect very prompt optical emission occurring within seconds of a GRB. This paper will present results from our attempts to follow-up observations of HETE2 triggers. We also present our plan to replace the current optical CCD camera on the Super-LOTIS to a near infrared camera to be able to probe dusty GRB environment.
This research is supported under NASA contract numbers S-03975G and S-57797F and under the auspices of the U.S. Department of Energy by University of California Lawrence Livermore National Laboratory under contract No. W-7405-Eng-48.
