The Pluto Occultation of a 12th magnitude star was a rare event and a lot of effort was being put into observing it. The programme for the early hours of June 30th that I was involved in was run by the South West Research Institute (SWRI) in Boulder Colorado.

A New Eclipsing Binary Star in Sagittarius
Simon Lowther
 
I present a new variable star in Sagittarius discovered during routine observations of V1223 Sgr for the Centre for Backyard Astrophysics, at CBA Pukekohe on 14th June 2014 NZST (JD2456822). The shape of the light curve suggests this star is an eclipsing binary of EW type with a period 0.2585 days and amplitude of 0.85 mag unfiltered. This star has been submitted to and accepted into the VSX catalogue of variable stars.

Bright Cepheids - A Variable Stars South Project
