摘要
Proper motions? positions, finding charts and magnitudes are given for 147 neu-ly discovered stars with proper motions larger than 0.15 arcsec/year. They were found in a search for high proper motion stars carried out in thirteen 5 degrees x 5 degrees areas, located between -30 degrees and -40 degrees in declination, and 00 h and 10 h 40 m in right ascension. Their blue photographic magnitudes range from approximately 9.0 to 18.5. Nine objects front the above sample have proper motions larger than 0.4 (0.404 to 0.550) arcsec/year. The same type of data is also presented for 149 Luyten Catalogue (LTT, Luyten 1957) stars re-discovered during the above search. An estimated precision level between 6 and 22 mas/year was achieved for the proper motions.
