History of observations
Discovery of SIPS 1259-4336 was published in 2005 by Deacon et al. The star was detected by its high proper motion from the Southern Infrared Proper Motion Survey (SIPS).
Distance
There is an unpublished trigonometric distance estimate from website en.allexperts.com: Tom Whiting e-mailed Todd Henry from RECONS team around 2008, and the reply was that theirs unpublished distance estimate of SIPS 1259-4336 is 7000779000000000000♠7.79±0.05 parsecs (7001254000000000000♠25.4±0.2 light-years).
As of May 2015, the only published distance estimates of SIPS 1259-4336 besides trigonometric parallax with high uncertainty from the star's discovery paper (6994133808575986232♠276±41 mas) is a parallax without error (~128 mas) from Burgasser et al. (2015). References of SIPS 1259-4336 data, including the parallax, were Deacon et al. (2005a) and T. Henry, priv. comm.
