Portion of the difference image obtained by subtracting the 2007 HST ACS/WFC F435W image (H1) from the 2013 HST ACS/WFC F435W image (H2). White objects were brighter in 2013 than in 2007. The ellipse represents the 3σ uncertainties in the X-ray position of T3: 0 farcs57 in R.A. and 0 farcs42 in decl. No counterpart was observed.
