 note = {The 3rd Suzaku international Conference "Energetic Cosmos : from Suzaku to ASTRO-H" (June 29-July 2, 2009. Grand Park Otaru Hotel), Otaru, Hokkaido Japan, We have observed two GRBs, GRB 071112C and GRB 080506, before the start of X-ray flares in the optical and NIR bands. In conjunction with published X-ray and optical data, we analyzed densely sampled light curves of the early afterglows and SEDs in the NIR to X-ray ranges. We found that the SEDs had a break between the UV and X-ray regions in the normal decay phase. No significant variation in the opticalNIR range was detected together with the X-ray flares, suggesting that the X-ray flares should be associated with a late internal shock. In addition, we found that two-component jets external shock model can also explain the observed variations of SEDs during the X-ray flares., Meeting sponsors: The University of Tokyo, The Institute of Physical and Chemical Research, The Japan Society for the Promotion of Science, 資料番号: AA0064574152, レポート番号: JAXA-SP-09-008E},
