Groups
Special Interest Groups
ASSA Special Interest Groups give members a way to go deeper into particular areas of astronomy, share practical experience and take part in projects with others who have similar interests.
Groups cover imaging, radio astronomy, dynamic solar system events, variable-star research, astronomy technology projects and support for women in astronomy.

People and community
Groups are not only about equipment and data. They are also places for members to ask questions, share experience, build confidence and meet others working in the same part of astronomy.

Observation and research
Some groups support citizen-science work where observations made by amateurs can be useful to researchers, including variable-star observations and time-sensitive solar system events.
Find a group
Astro-Imaging
For members interested in capturing and processing astronomical images.
Members image deep-sky objects, planets, comets, the Milky Way, auroras and other astronomical phenomena using everything from camera lenses to advanced telescope and camera systems.
- Monthly online Zoom meetings, usually on the Tuesday closest to full moon.
- Image sharing, feedback and technical discussion.
- Astro camps at dark-sky locations several times a year.
Radio Astronomy
For members interested in detecting astronomy through radio signals.
Radio astronomy opens up parts of the universe that are invisible to optical telescopes. Members explore receivers, antennas, signal processing and natural radio-emitting sources.
- Pulsars, solar activity and Jupiter radio storms.
- Software-defined radio and custom-built receiving equipment.
- Technical projects, reference material and member observations.
COMA
Comets, Occultations, Meteors and Asteroids.
COMA focuses on dynamic solar system objects and time-sensitive observing events, including comet apparitions, meteor showers, asteroids and occultations.
- Local information exchange for fast-changing observing opportunities.
- Comet and meteor observing sessions.
- Encouragement for members to participate in asteroid occultation events.
Variable Stars
For members interested in stars whose brightness changes over time.
Variable-star observations can be made visually, with binoculars, with a small telescope or with imaging equipment. Useful observations can be made from suburban back yards.
- Citizen science projects linked to international observing networks.
- Connections with AAVSO and Variable Stars South.
- Chat, email support and training when demand is sufficient.
Technology
For members who build, adapt, document and share astronomy-related technology.
Astronomy involves a lot of technology, from checking weather and sky brightness to controlling telescopes, recording data and solving practical equipment problems.
- Electronics, mechanical projects and software.
- Dew heaters, timing systems, 3D printed parts and telescope support tools.
- Weather, sky-brightness, seeing and seismic monitoring interests.
Mary Emma Greayer Group
Supporting the participation of female astronomers within ASSA.
Mary Emma Greayer was one of the first female ASSA members, joining in 1893. The group supports women, particularly younger women, to build astronomical knowledge, skills and confidence.
- Named for an early ASSA member who worked at the Adelaide Observatory.
- Connects members through events and an online group.
- Point of contact: Mary Adam.
How to take part
Most Special Interest Group activity is intended for ASSA members. Meeting details, Zoom links and member notices are generally circulated through ASSA member channels. If you are not yet a member, you can still use these pages to see the range of interests supported by the Society.
