Arai, report on behalf of the KANATA GRB team:\n\n  We continue the observation of GRB 080810 with the KANATA 1.5-m \ntelescope.  We obtained V, J, and Ks-band images of the field \nof the afterglow using TRISPEC.\nThe latest observation shows:\n\ntime(UT)    mag.   err   exposure time\nAug. 2008  \n10.78444   18.92V  0.05   123sec * 10\n10.78479   17.53J  0.31    72sec * 10\n\nThe light curve we obtained can be described with a simple \npower-law decay between 420 and 20000 sec after the GRB trigger, \nwithout an apparent break.  \nThe power-law index is calculated to be 1.21+/-0.02. \nThe index is slightly, but significantly larger than that reported \nin GCN 8084, implying a possible break around the very early \nor very late phase of our observation period.  \n\nFurther monitoring is encouraged.",
