W. Li, confirmed 2006A on a Lick Observatory image from Jan. 5.108 (Boles measuring position end figures 03s.81, 55".6 from the KAIT image). Traces of 2006A are also visible on an unfiltered CCD image taken by G. Rogers (Long Crendon, England, 0.40-m reflector) on Jan. 4.794. Nothing is visible at this position on Boles' images from 2005 Sept. 24 and Oct. 10 (limiting mag 19.5) or on Digitized Sky Survey images from 1991 (limiting red mag 21.0) and 1993 (limiting blue mag 20.5).
