This is followed by a flattening and possibly a plateau phase coincident with a similar feature in the X-ray. We discuss these observations in the framework of the standard reverse shock/forward shock model and energy injection. The plateau phase might also be the signature of the formation of a new magnetar.gamma-ray burst general10.1051/0004-6361/201116794http://adsabs.harvard.edu/abs/2011A&A...530A..74G2011A&A...530A..74G
