The Trans Tasman Occultation Alliance
An observing section of the Royal Astronomical Society of New Zealand
welcomes you to its Web site.

---

Occultations occur when one celestial body passes in front of another.
These frequent and intriguing events are fun to watch, and provide an important way for amateur astronomers to make significant discoveries about objects within our own Solar System as well as the stars beyond.

 

This website exists to promote and encourage occultation
observing in New Zealand, Australia and the South Pacific.

 

On this site you will find information about different sorts of occultations, and how to contribute useful scientific results by observing occultations.
The site contains all the background information needed by someone new to occultation observing. It also provides more technical information of use to advanced observers.

The Trans-Tasman Occultation Alliance is also proud to represent the interests of the International Occultation Timing Association (IOTA) in the Australasian region.
