摘要：

We report the identification of the optical counterpart of the X-ray transient XTE J1550-564 described in two companion papers by Sobczak et al. and Remillard et al. We find that the optical source brightened by approximate to 4 mag over the quiescent counterpart seen at B approximate to 22 on a SERC survey plate and then decayed by approximate to 1.5 mag over the 7 week-long observation period. There was an optical response to the large X-ray flare described by Sobczak et al., but it was much smaller and delayed by approximate to 1 day.
