Below is a graph showing all measured TASS positions of this star and all nearby stars, as well as positions of bright stars in USNO B1.0.
Below is a graph showing unweighted linear fits to the position in each direction as a function of time. The slope of each line yields proper motion in arcseconds per year.
Any TASS proper motion significantly above uncertainty will be highlighted below

Below are cutouts from POSS I (approx 1955), POSS II (approx 1990), 2MASS (approx 1999), loop (refresh to repeat loop). Each cutout is 90 arcsec wide.
