Huang\non behalf of EAFON report:\n\n\"We have monitored the optical afterglow of GRB080310 (Cummings et al\nGCN 7382) on the night of March 10th using the Mt. Lemmon 1m and the\nLulin 1m telescopes. These time coverage are 09:26 -- 12:54 UT\n(Mt. Lemmon) and 15:52--21:16 UT (Lulin), respectively. All of images\ntaken with 300 sec exposure in V and R band show the afterglow clearly.\n\nBased on our preliminary results calibrated using USNO-B1.0 catalog,\nwe confirmed the decaying light curve with a power-law index 0.7+/0.1\nbetween 0.8 and 2.1 hours after the burst. This result is consistent\nwith the observations by the LBT (Garnavich et al., GCN 7390) and the\nROTSE-III (Yuan et al., GCN 7411).  The light curve between 7.3 and\n12.2 hrs after the burst is well described by single power-law with\nindex 0.8+/-0.1 in R-band. The extrapolation of this power-law is also\nconsistent with the observation by the LBT (Garnavich et al. 7409).\nWe could not confirm the plateau phase reported by the MITSuME (Yoshida\net al., GCN 7410).\"\n\nThis message may be cited.",
