Possible Optical Detection of the Anomalous X-ray Pulsar CXOU   J010043.1-721134
  Archival Hubble Space Telescope Wide Field/Planetary Camera 2 observations of the Small Magellanic Cloud serendipitously reveal a possible counterpart to the Anomalous X-ray Pulsar CXOU J010043.1-721134. The candidate is faint, but its location and strange colours make it an interesting object. We estimate, that the probability of such a detection being due to a non-physical source is less than 1.5%. We have tried to confirm the identification with Gemini-South and Magellan, but the conditions were insufficiently favourable. If confirmed, the object will allow the first detailed studies of the optical and ultraviolet emission of magnetars.
