"The physical nature, distribution, formation and evolution of asteroids are fundamental to our understanding of how planet formation occurred and, ultimately, why life exists on earth.  In our current solar system, asteroids (and comets) are the most direct remnants of the original building blocks that formed the planets."

"Interpreting this record via observation, laboratory studies of meteorites, and theoretical/numerical modelling can tell us much about how the bodies in the solar system have evolved with time."

  • Photometry : Obtain, analyse and report the brightness variations of Minor Planets. Obtain, Analyse and report the brightness variations of AAVSO and VSS variable stars targets and newly discovered variable stars;
  • Astrometry : Obtain, measure and report the position of Near Earth Objects (NEOs) to a high degree of precision in a timely manner
  • Spectroscopy : Obtain, analyse and report the Specrta for newly discovered variable stars and objects of critical interest to the AAVSO and VSS;
  • Education : Provide an extensive reference on the observational aspects of astronomy and where appropriate, details of analystical techniques and tools.
