The Diurnals

Contributed by Pat Larkin

The DIURNALS is a friendly group which meets during the daytime on the third Tuesday of the month February - December.


To provide an opportunity for meetings during the DAYTIME.

To disseminate knowledge on various facets of astronomy and related fields, together with Space Exploration, in an informal environment.

To foster enjoyment of the subject matter with kindred spirits, and to encourage newer members who may show an interest in a particular area.

There are no pre-requisites and you don't have to be a mathematics or physics genius! Just come with a desire to learn.  Most months, we have a guest speaker, and talks given cover a wide range of astronomical fields and space exploration. Occasionally, a film is shown followed by discussion if desired.   Two or three times a year, we will have an excursion to another facility, e.g., Swinburne University, Melbourne Planetarium or a Science facility.



Next Meeting:            Tuesday, 16th April 2019. 

TIME:                        10.30 a.m.  - 12.15 p.m.

PRESENTER:           Rod Brown - ASV


After briefly mentioning celestial navigation and the Polynesian navigators, Rod will speak on navigational instruments of the 17th, 18th and 19th centuries, and the measures undertaken to establish their benefit as well as having them accepted. Rod will then bring us into the modern era of satellites and the global positioning system.

Rod has previously presented to Diurnals :  2006 - The Distance Estimators, 

                                                                      2007 - Tides and Early Efforts in Their Prediction,

Members may like to bring along a cut lunch and chat further with the presenter.  This is always a nice time to share  with kindred spirits.
