Scientific paper

Numerous star systems within 33 parsecs of our Sun remain to be identified, in particular low-mass stars with relatively small proper motions. We present the identification of 1412 new stars within 33 parsecs of the Sun, including 7 new stars within just 12 parsecs, from the SUPERBLINK proper motion survey. We searched the database of 1.6 million SUPERBLINK stars with proper motions between 0.04 and
0.15 seconds of arc per year, covering the entire northern sky. Photometric distances were calculated from infrared and optical colors and magnitudes (from the 2MASS and USNO-B catalogs). Infrared color cuts were used to eliminate background giants. A list of the nearest new stars is presented.
