New high proper motion star at (R.A., decl.) = (223.°7678, +33.°7066) discovered serendipitously in DR6 of the Legacy Surveys. The left and right panels show ≈67 × 67″ cutouts of the SDSS and DR6 images, respectively, extracted from the Legacy Surveys’ image viewer (http://legacysurvey.org/viewer); north is up and east is to the left. The g = 21.2 AB mag M0V star (classified based on an SDSS spectrum; https://dr12.sdss.org/spectrumDetail?mjd=54942&fiber=500&plateid=3315) is moving at ≈0.″2 per year. The large time baseline (≈14 yr) between the SDSS and Legacy Surveys data will enable proper motion measurements for stars fainter than the Gaia DR1 catalog limits.
