Wang and the TAOS\nteam\n\nThree 50cm TAOS telescopes, located at Lulin observatory, Taiwan,\nstarted to observe GRB 090424 field (Cannizzo et al.; GCN 9223) at 94s\nafter the trigger. The optical afterglow (Yuan et al., GCN 9224; Xin\net al. GCN 9225) was clearly detected in images taken by TAOSA (25s\nexposure), TAOSB (5s exposure), and TAOSD (1s exposure). Brightness of\nthe afterglow is about R~13.08 at 94s post the burst. Our R-band\nmagnitude were calibrated with USNOB red stars.\n\nthis message can be cited",
