In paper 167 of his serie published in The Observatory, Griffin presented the
spectroscopic orbit of HD 112914, a late main sequence star. He also noticed
that this star, also known as HIP 63406, was one of the few for which the
DMSA/O Annex of the Hipparcos Catalogue derived an orbit prior to any
spectroscopic one. Albeit in agreement with each others, the astrometric orbit
was however determined with rather large uncertainties. Here, we have
reanalysed the Hipparcos Intermediate Astrometric Data (IAD) using
Griffin'spectroscopic orbit to obtain a much more precise astrometric orbit.
Several parameters of the HD 112914 system are now well constrained.Comment: 4 pages, 1 figure; accepted for publication in The Observator
