摘要

Utilizing East Asian GRB Follow-up Observation Network (EAFON), we have obtained 3 major results; 1) first long-term monitoring of short GRB afterglow from ∼ 0.1 days after the burst, 2) multi band monitoring of early optical shallow decay and re-brightening phase, 3) catch about 30 high-redshift GRB candidates. In this paper, we present shallow decay phase and re-brightening phase of early optical afterglow. Our results imply that these phases are unlikely to be caused by the variable external density model. Overall 1 day light curve behavior may be explained by Patchy shell model and/or different emission region such as 2 jets model rather than to be described by refreshed shock scenario.
