Difference between the positions of the proposed companion to HN Peg at various epochs, and its 1998.7 2MASS position, updated assuming common proper motion with HN Peg. The astrometry derives from images obtained with IRAC (2004.4), SOFI (2006.5), WIRCam (2006.7, 2007.3, and 2007.5), and NSFCAM2 (2007.7).
