Schröter, William Herschel and the Mountains of
Since the invention of the telescope the observations of atmospheric phenomena regarding Venus have always proved difficult. Some early observers reported variations in the curvature of the cusps and so-called "terminator anomalies". It was these particular anomalies and their interpretation that lead to a somewhat passionate debate, mainly between Friedrich Wilhelm (later William) Herschel (1738-1822) and his fellow compatriot Johann Heironymous Schröter (1748-1816). Schröter assumed that the direct cause of the irregularities, especially near the southern cusp, was a mountain or a mountain range - a Venusian Himalayas, while Herschel concluded the 'alleged' cause of the Venusian anomalies could possibly be attributed to Schröter's tarnished speculum mirror. This paper also discusses the life and observations of Shröter and attempts to explain the basis of his reputation as a poor and unreliable observer.

Want to get dizzy? Just step into Possum Observatory - a 3.4m x 3.1m rotating building and you'll walk through the observatory door in one part of the backyard and then out the door in a different part of the backyard! This article recalls how I made this rotating observatory, what scopes I have in it, and what astronomical work I am doing.

A Lifetime of
Reg C Sutherland.
When we are very young, sometimes an event will capture our imagination and we will continue to pursue the phenomenon for the rest of our lives. In my case, while living at Pukemaori, away in the South, I saw a spectacular auroral display during the mid-1930s. The sky was ablaze with flashing coloured lights. I was told it was caused by sunlight reflecting of the ice in the Antarctic. How wrong they were!

Roemer and the
Speed of Light
In 1676 Roemer published a paper in which he established the finite speed of light from observations of the times of eclipses of the satellite Io, the innermost of Jupiter's Galilean satellites. His method for doing this can easily be adapted by observers to make their own estimates of the speed of light. Fairly short term variations in the period of Io limit the accuracy which can be obtained.

During the 2003 very close opposition of the planet Mars, a number of New Zealand amateur astronomers took images of the planet through their telescopes. Many took advantage of the relatively inexpensive Philips ToUcam 'Webcam'; a small video camera used at a computer for videoconferencing. This is one person's experiences.

The 2003 Carter Memorial Lecture was given in May by Dr Ben R Oppenheimer, Kalbfleisch Research Fellow in the Department of Astrophysics at the American Museum of Natural History in New York. Public lectures entitled "Aliens: The Scientific Search for Life on Other Planets" were given in Nelson, Dunedin, Christchurch, Wellington, Wanganui, Napier, Hamilton and Auckland. University seminars entitled "The Lyot Project" were given in Christchurch, Wellington, Hamilton and Auckland.

the Thomas King Telescope at Carter Observatory
In May 2001 I began the refurbishment of the 5inch Grubb Telescope housed in the Thomas King Observatory. This telescope was made in 1882 by Grubb in Dublin and over its 120 years it is in remarkably good condition.

Aspects of the
Restricted Three Body Problem
An extended version of a talk presented at the 2003 RASNZ conference in Christchurch. This paper preents a study of asteroi motions near the L4 and L5 Langrangian points in the restricted three body problem. Where the asteroid remains close to the L4 or L5 points, some analysis is possible which reveals rich behaviour abd an unexpected relationship involving Pythagorean triplets.

System: Sharing Observing Logs on the Internet
A large number of amateur astronomers in New Zealand and around the world keep logs of their observations. One disadvantage with observing logs for some people is that they are not normally accessible to anyone besides the person who made the observations. In the past decade, computers and more recently the Internet have made it easier for information to be organised and propogated widely. This article presents a new method for astronomical observing logs to be published online via a central website, allowing people to keep ttrack of hat everyone else is doing, and communicate about their activities.

To Learn or to
Understand in Science Education
Frank P Andrews.
The Carter Observatory has been involved in education since it began operation in 1941. In the sixty years since its founding this education programme has steadily developed in scope and student throughput. The present programme is dedicated to enthusing students in science and astronomy as well as the related areas of scientific understanding. We stress participation and gaining understanding in our approach. In this paper we look at the vital difference in approach and outcomes between students who are expected to learn science as opposed to those gaining an understanding of the subject and look at how we are dealing with astronomy instruction at Carter Observatory.
This paper was delivered at the 2003 RASNZ conference. This is a corrected version of the paper originally printed in Volume 42, number 3, September 2003.

Ever. Honest!" - Behind the Hype.
Keen sunspot observers are still reeling from the fantastic sloar activity of the last few years (and months), which encompassed the maximumof Solar Cycle No. 23. This cycle seems to have produced some of the greatest flares so far recorded. But are they?
