Scientific paper

We note that the B supergiant HD 306414 (Tycho coordinates RA: 11 21 46.807, Dec: -59 51 47.93) lies only 16" away from the nominal position for the new INTEGRAL transient IGR J11215-5952 (ATel #469). From 2MASS and USNO-B1 archival data analyses, HD 306414 is the brightest optical object in the 3' error circle, though there are three brighter IR sources, namely 2MASS J11214129-5953035 (K=7.15, b=15.3), 2MASS J11220105-5950185 (K=6.10, b=12.8) and 2MASS J11220165-5952502 (K=8.05, b=19.2).
