Abstract
⺠Our original Apophis astrometry suffered from bias. ⺠The use of the 2MASS astrometric catalog reduces the bias and improves the astrometry of Apophis. ⺠Over 430 observations of Apophis now show an RMS error of only 0.12 arcsec. ⺠Telescope tracking inconsistency is now recognized as a source of additional error.
