Brian Mason - from the New Zealand Mainland, to Meteorites, and Moon Mountains
After giving my talk at Stellarfest about meteorites in which I discovered the illustrious career of Brian Mason and his role in identifying lunar meteorites, a member suggested a piece in Southern Stars might be appropriate. Dr Mason died in 2009 at the age of 92 and there is a Wikipedia page about him, but I found a wealth of information in the little booklet ''œFrom Mountains to Meteorites'' which was put out by the NZ Geological Society. I am continuously amazed at the accomplishments of New Zealanders who go offshore to further their field of study.

More on Astronomy in Wellington in the 1840s
Wellington pioneers with astronomy connections were J. Hurley, J. H. Marriott, R. Sheppard and also W. M. Smith and C. Grace. Local newspapers recorded two comets seen in Wellington in the 1840s, while of these five pioneers, one was a sawyer and timber merchant, one made and repaired telescopes, two were surveyors and one taught astronomy.

The KPO Weather Station
The idea behind my building of a weather station goes back to 1993 when the Carter Observatory C14 with a Compustar built into it was installed in my observatory. First we had to try to automate the telescope which was not easy. Once we achieved automation we needed to automate the dome. Once this was achieved we needed a way of closing the dome in the middle of the night while we slept. If the wind rose to say 20 knots or more the dome would rotate to its park position and then close the shutter which opened like a clam shell and then parked the telescope and shut the dome and close down the power so the only equipment left running was the computer.

Looking for all the world like a second-hand car yard in the middle of a cow paddock, Awarua Satellite Ground Station looks perhaps a little unprepossessing.

The First Great September Filament
R. W. EVans
During September 2013, astronomers observing the Sun in Hydrogen-alpha light witnessed the exciting activity of two long-lived filaments/prominences:- increasingly called 'filaproms' when they are observed both on the Sun's disc as dark filaments and then on its limb as bright prominences.

Monitoring Our Skies - How do we know if we are successful?
Why should we monitor the sky? We don't know whether light pollution is getting better or worse over time. We need to establish a baseline of where we are at the moment and repeat the process in a five year cycle. Adapted from a presentation to the Royal Astronomical Society of New Zealand conference in Invercargill in May 2013.

Southern Constellation Names
La Caille's first catalogue gave constellation names in French (de la Caille, 1756) and his second in Latin (de la Caille, 1763), which had been for centuries the standard international language for European scholarly work. EVen now the International Astronomical Union (IAU) uses it for constellation names. This paper is about what happened after La Caille's time.

Dual Maxima Mira Variable Stars
Amongst Mira Variable stars with periods in excess of 400 days is found a small group which show two maxima in each cycle. Two of these have shown dramatic period changes. Other Miras with period changes may once have been members of this group. Light curves, colours and other behaviour are described as well as a curious distribution in the sky.

La Caille and the Far Southern Sky
The Abbé Nicolas-Louis de La Caille (1713-1762) is one of the early European explorers of the far southern sky. This essay discusses La Caille's new southern constellations as represented by Anne-Louise Le Jeuneux in a magnificent oil painting dated 1755. Along the way it also reviews new books by Ian Glass and Nick Kanas.

Southern Close Binaries Programme of the VSS
R Idaczyk, M Blackford, E Budding, R Butland
We review the programme of studies of southern close eclipsing binary systems that has been underway in recent years, involving observations at the Mt John University Observatory and elsewhere in the region. We include brief descriptions of equipment used, before presenting summary results on four typical examples (U Oph, V831 Cen, R CMa and η Mus) drawn from the programme. We show that absolute stellar parameters thus obtained are of high enough quality to compare favourably with any other recent data in this field. Thus, for U Oph, we derived a new value for the third star's mass, and an age consistent with the system's origin in Gould's Belt. We announced the chemical peculiarity of the third star accompanying V831 Cen. Our new parameters for R CMa solve the longstanding 'overluminosity' issue, although the close pair must have lost considerable angular momentum. For η Mus, we discovered another member of the system that removes the problem of the (otherwise) anomalous radial velocity of η Mus B. Such new findings encourage interest in further pursuit of the programme.

The VSS Southern Eclipsing Binaries Programme
Yes, astronomy is fascinating and exciting to read about. And yes, it's fascinating and exciting to see the denizens of the sky through a telescope or to capture them with an image. But how about doing some astronomy; contributing to the science instead of just absorbing it? Eclipsing binaries offer a way in that's simple, un-demanding of equipment, doesn't need you outside all hours of the night, produces exciting results out of every night's imaging, and can even be done on a computer instead of a telescope. The Southern Eclipsing Binaries Programme of Variable Stars South is designed to provide all of that to the beginner in astronomical research, as well as keeping the experts Very busy.
