Yoshida (Hiroshima Univ.) report on behalf of Kanata team:\n\nWe performed a series of optical imaging polarimetry for the optical \nafterglow of GRB 120212A (Guidorzi et al.; GCN 12932) using HOWPol attached \nto the 1.5-m Kanata telescope at Higashi-Hiroshima Observatory, Japan. \n\nOur first exposure began at t=74 sec since Swift/BAT trigger (Sonbas \net al.; GCN 12930), but the bright twilight sky shaded the afterglow \nuntil t=22 min. Our quick-look analysis indicates that Rc magnitude of \nthe afterglow was 16.5 at t=23 min and faded to 17.6 at t=58 min. \nFurther analysis is ongoing.",
