P.J.Booth Editorĥ ASTRONOMY IN SOUTHERN AFRICA Southern Africa, enjoying the rich southern skies and a suitable climate, has a number of professional observatories engaged in research while many individuals have become enthusiastic amateur astronomers. The ASSA regrets that due to the restriction of funds it is not possible to print this handbook in any of the other official languages of South Africa. Further copies of this booklet are available at RIO,00 per copy from The Business Manager, Astronomical Society of Southern Africa, P O Box 9, Observatory, All other correspondence concerning this booklet should be addressed to the Handbook Editor, Astronomical Society of Southern Africa, 10 Bristol R d., Observatory, Although every care has been taken in the compilation of the Handbook,it is sold and distributed on the explicit understanding that neither the Society nor its members accept any responsibility for errors therein.
Assistance in the compilation of this booklet was received from the Directors of the sections of the ASSA. Josef de Kerfo, General Manager of Agfa-Gevaert I W (Mortsel, Belguim) for making the computing facilities available. The Minor Planet Occultations were provided by Edwin Goffin, who wishes to thank Dr. Bondietti, published by the South African Museum. The star charts on pages 32, 34, 36 and 38 are from "A Beginner's Guide to the Southern Stars" by J.S. The data it contains has been adapted for Southern Africa from data obtained from The Astronomical Almanac for 1995, the Handbook of the British Astronomical Association for 1995 and the International Lunar Occultation Centre,Tokyo. This handbook is produced for the Astronomical Society of Southern Africa. Right Ascension and Declination are given for equinox of date unless otherwise stated.

These examples are programmatically compiled from various online sources to illustrate current usage of the word 'parallax.' Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors. Susan Tallman, The New York Review of Books, 29 Dec. 2022 And because parallax shift is proportional to the distance between the objects in view, a flattish curtain raises fewer problems than, say, trees in a field.
The Physics Arxiv Blog, Discover Magazine, 15 Nov. 2015 This parallax method then reveals the distance of the nearer stars. oregonlive, 21 June 2021 In 1838, Bessel observed the apparent back-and-forth movement of the star 61 Cygni that results from our shifting perspective as Earth orbits the sun, an effect known as parallax. Ashley Strickland, CNN, 14 June 2020 This is called parallax. 2023 The stars appeared to be in different locations through the parallax effect, meaning that the stars seemed to shift against the background since New Horizons was viewing it from a different view point. Andrew Dyer, San Diego Union-Tribune, This information, along with the parallax distance, enabled The Times to calculate the balloon’s height using the geometric properties of similar triangles. 2023 To explain the apparent rotation, West pointed again to the ATFLIR pod and the parallax effect. Recent Examples on the Web During the competition, the robot’s head could be seen shifting from side to side as the operator used parallax to understand how far away objects were.
