We decompose the early onset bump and the late re-brightening bump with empirical fits and analyze their statistical properties. Among the 146 GRBs that have well-sampled optical lightcurves, the onset and re-brightening bumps are observed in 38 and 26 GRBs, respectively. It is found that the typical rising and decaying slopes for both the onset and re-brightening bumps are ~1.5 and -1.15, respectively. No early onset bumps in the X-ray band are detected to be associated with the op","authors_text":"Bing Zhang (UNLV), En-Wei Liang (GXU), He Gao (UNLV), Jian-Yan Wei (NAOC), Jie-Min Chen (GXU), Jin Zhang (NAOC), L.
