The UKIDSS Galactic Plane Survey (GPS) began in 2005 as a seven year effort to survey ~1800deg^2^ of the northern Galactic plane in the J, H, and K passbands. The survey included a second epoch of K-band data, with a baseline of two to eight years, for the purpose of investigating variability and measuring proper motions. We have calculated proper motions for 167 million sources in a 900deg^2^ area located at l>60{deg} in order to search for new high proper motion objects. Visual inspection has verified 617 high proper motion sources (>200mas/yr) down to K=17, of which 153 are new discoveries. Among these, we have a new spectroscopically confirmed T5 dwarf, an additional T dwarf with estimated type T6, 13 new L dwarf candidates, and two new common proper motion systems containing ultracool dwarf candidates. We provide improved proper motions for an additional 12 high proper motion stars that were independently discovered in the WISE data set during the course of this investigation.
We present the discovery of about 100 new high-proper motion stars in the region between 0^h^ and 7^h^ in right ascension and -63{deg} and -32{deg} in declination, with proper motions between 0.3 and 1.0arcsec/yr. In addition we have obtained improved coordinates and photographic photometry for another about 100 already known high-proper motion stars in the same region. In this study we have made use of APM measurements of UKST survey plates in 40 survey fields. Using all available information (position, proper motion, photographic R magnitude and B_J_-R colour index), we draw some preliminary conclusions on the nature of the new high-proper motion stars, particularly of extreme cases.
We report 1606 new proper-motion systems in the southern sky (declinations -90{deg} to -47{deg}) with 0.40"/yr>{mu}>=0.18"/yr. This effort is a continuation of the SuperCOSMOS-RECONS (SCR) proper-motion search to lower proper motions than reported in Papers VIII, X, XII, and XV in this series. Distance estimates are presented for the new systems, assuming that all stars are on the main sequence. We find that 31 systems are within 25pc, including two systems (SCR 0838-5855 and SCR 1826-6542) that we anticipate to be within 10pc. These new discoveries constitute a more than 10-fold increase in new systems found in the same region of sky searched for systems with mu>=0.40"/yr, suggesting a happy hunting ground for new nearby slower proper-motion systems in the region just north (declinations -47{deg} to 0{deg}), much of which has not been rigorously searched during previous efforts.
Data are given for 548 new proper-motion stars with {mu}>0.15arcsec/year found on 23 areas covering 25 square degrees each. These are located south of declination -40deg and between 16h and 24h in right ascension. Photographic magnitudes range from 10.0 to 20.0. Twenty stars have proper motions larger than 0.5arcsec/year a magnitude range between 14.0 and 19.5
Data are given for 494 new stars with proper motion larger than 0.15arcsec/year found on 21 areas covering 25 square degrees each. These are located between -5deg and -30deg in declination and between 0h and 9h in right ascension. Photographic magnitudes range from 9.5 to 19.0. Eight stars have proper motions larger than 0.5arcsec/year, in a magnitude range between 15.5 and 19.0.
This table presents relative proper motions and positions for 293 stars with proper motions larger than 0.15 arcsec/year, discovered as a result of a program to identify fast moving stars in the southern hemisphere, being carried out with the Maksutov Astrograph at the Estacion astronomica de Cerro el Roble
Data are given for 492 new stars with proper motion larger than 0.15arcsec/year found on 21 areas covering 25 square degrees each. These are located between -5deg and -30deg in declination and between 9h and 13h30m in right ascension. Photographic magnitudes range from 9.5 to 18.5. Four stars have proper motions larger than 0.5arcsec/year, in a magnitude range between 15.5 and 17.5.
Here we present 1584 new southern proper motion systems with {mu}>=0.18"/yr and 16.5>R_59F_>=18.0. This search complements the six previous SuperCOSMOS-RECONS (SCR) proper motion searches of the southern sky for stars within the same proper motion range, but with R_59F_<=16.5. As in previous papers, we present distance estimates for these systems and find that three systems are estimated to be within 25pc, including one, SCR 1546-5534, possibly within the RECONS 10pc horizon at 6.7pc, making it the second nearest discovery of the searches. We find 97 white dwarf candidates with distance estimates between 10 and 120pc, as well as 557 cool subdwarf candidates.
