discov_num notes refcode
RED 20 One companion is ~10" from CD-29 1020 = 2MASS J02481094-2835382. To
the SW at a milar distance is 2MASS J02480263-2835465. There are no
USNO-B1 proper motions for the fainter stars, but comparison of
Digitized Sky Survey UKST and 2MASS images show little evidence of
significant relative motion. IR colors are consistent with a K0/M3/M6
triple at 60pc. System appears non-hierarchical, with projected
separations of ~600au between each component. Red2007a
