WIDGET is a robotic telescope for monitoring the HETE-2 field-of-view todetect Gamma-ray Burst optical flashes or possible optical precursors. Thesystem has 62degx62deg wide field-of-view which covers about 80% of HETE-2 onewith a 2kx2k Apogee U10 CCD camera and a Canon EF 24mm f/1.4 wide-angle lenswithout a bandpass filter. WIDGET has been in operation since June 2004 atAkeno observing site where is about 200 km apart from Tokyo. Typical limitingmagnitude with S/N=3 at the site is V=10mag for 5 seconds exposure and V=11magfor 30 seconds exposure. We had already six coincident observations with HETE-2position alerts. It was, however, cloudy for all cases due to rainy season inJapan. Expected number of coincident observations under clear sky is about 5events per year. We will extend the system in early 2005 for Swift era tomonitor optical transients in wider field-of-view, multi-color or polarizationmodes.Comment: 4 pages, 4 figure.
