Full financial membership of the RASNZ Occultation Section (RASNZ/OS) costs $NZ 35.00 per calendar year and provides a number of benefits.
Two of these benefits are subscriptions to our two major occultation publicatons - the RASNZ Occultation Section Circulars, and the Journal for Occultation Astronomy published by the International Occultation Timing Association (IOTA).
If you are already a financial member of the Section you can use the member login and password issued with your membership to download current and past publications from our member/downloads area:
If you are not currently a member of the Section you'll find information about membership on our Membership Page.
RASNZ/OS Circulars are published exclusively as PDF files available for download from our website. They contain detailed reports from observers, provide analysis and feedback, give advance warning of upcoming lunar and planetary occultations, and contain general news likely to be of interest to all occultation observers. In the past we have published Circulars on a quarterly basis, although over the years 2008-2011 our publications were in abeyance. At present we are publishing Circulars as quickly as we can until our publications are fully back on schedule.
The Asteroidal Occultation Circulars (CA series) which were published up untll 2008 have been discontinued as their function has largely been superseded by our online planetary occultation predictions and the common use of Hristo Pavlov's excellent OccultWatcher software.
For an example of what our News Circulars contain please download a free sample:
Circular CN2007/4 - March 2012 (5.9Mb MB PDF / 64 pages)

Submitting Material for Publication in the RASNZ/OS Circulars::
- These are edited by Murray Forbes, who is pleased to receive contributions on any occultation-related topic. He is particularly keen to obtain articles written at a popular level which illustrate both the joys and frustrations of occultation observing.
The RASNZ/OS distributes to its members, on behalf of the International Occultation Timing Association, the Journal for Occultation Astronomy (JOA). This publication is produced quarterly by the European Section of IOTA, and replaces the previous Occultation Newsletter publication which had appeared since the 1980s.
Free samples of the JOA are available from the links below:
