Photographic magnitudes, absolute trigonometric parallaxes, positions, and proper motions are presented for 45 Tauri, 97 Tauri, 102 Tauri, 31 Cygni, and about 80 additional stars in their vicinities. An absolute parallax of 0.032 (+ or - 0.008) arcsec is determined for 45 Tauri along with an absolute visual magnitude of 3.27 + or - 0.54 and a space motion of approximately 41 km/s. The respective values obtained for 97 Tauri and 102 Iota Tauri are: (1) 0.020 (+ or - 0.007) arcsec, 1.61 + or - 0.58, and about 40 km/s; (2) 0.020 (+ or - 0.004) arcsec, 2.3, and 46 km/s. An absolute trigonometric parallax of 0.005 (+ or - 0.003) arcsec is determined for 31 Omicron-2 Cygni. It is noted that the proper motion of 102 Tauri is consistent with membership in the Hyades cluster.
