L. ; Upgren, A. R. Abstract Parallaxes and proper motions are presented for 30 stars, most of which are dK-M stars in 20 star fields. Seven of the target stars as well as ten other stars have no previous parallax determinations. Six of the 20 target stars are actually resolved binaries for which both components were measured separately; two of the six are not physical pairs. As in the previous lists in this series, reductions have been made using linear plate constants and results are given to the nearest ten-thousandth of a second of arc and separately in x and y coordinates along with a combined solution. This list is the first in the series which makes full use of the prior selection of parallax stars to achieve the primary goal of the Van Vleck parallax program. This is to determine accurate physical properties and space motions of a large and unbiased sample of unevolved nearby stars of the lower main sequence.
