A comparison of 2009 and 2010 observations at IRSF around the target position. North is up and east on the left side, and the horizontal line corresponds to 5 arcsec. The amplification of the source is obvious in the 2009 frame, while two stars are clearly separated in the 2010 frame: the westernmost star at the centre of the chart is our target. A third faint component north of the two other stars is also visible.
