Graeme Jenkinson has published a paper on nine neglected southern multiple systems in the Webb Society Double Star Section Circulars.

Abstract

Through the second half of 2014 measurements were completed of the following southern multiple stars as listed in the Washington Double Star Catalogue. Using a 400mm f4.5 Newtonian reflector fitted with a Meade DSI 2 camera and software program Astroplanner V2.1 (Rodman) the obtained images were analysed using Losse’s Reduc software. The mean 95% confidence intervals for the new measures were ± 0◦.576 in PA and ± 000.24 in separation.
