(3929) Carmelmaria Main-belt Asteroid
Discovered on 16 November 1981 by P. Jekabsons at Bickley.
Named in honor of Carmel Maria Borg (née Materazzo), secretary at the Perth Observatory and administrative assistant to three directors over 17 years. Her devotion to observatory projects, attention to detail and public-relations skills have seen the Perth Observatory through some turbulent times and played a large part in the successful interaction the observatory enjoys with the local community. She has also played a major role in preserving many of the observatory's historical documents and artifacts. Name suggested and citation provided by J. Biggs and P. Birch.Naming citation (WGSBN Bull. 6, #10, 5), IAU / Minor Planet Center, via NASA/JPL
