TASS PM candidate 243618

Basic information from TASS 'patches' dataset.

 
 TASS ID          RA          Dec     nobs       V   stdev   ens      I   stdev   ens   WSpos

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
