GRB090408 : TAOS optical observations

S.K. King, K.Y. Huang, S.Y. Wang and the TAOS team

The four 50cm TAOS telescopes observed GRB 090408 position (Stroh et
al, GCN9110Not found
 
 
) at 91s after the burst. No new optical emission was
detected in the BAT possition error range. The 3-sigma limiting
magnitude, compared with USNOB red stars, are as follows:
