The article reports on the discovery of the comet C/2009P1 by astronomer Gordon Garradd in Australia on August 13, 2009. It observes that the comet brightens slowly as it moved through the southern skies, and it continues its northerly track throughout 2010 and emerged from conjunction with the Sun for the second time to become visible in Aquarius. Garradd describes the comet as a tailless object with an approximately circular coma of diameter 15 inches.

The article reports on the discovery of comet, designated C/2011 W3, by amateur astronomer Terry Lovejoy in Brisbane, Queensland on November 27, 2011. It determines that the comet was a member of the Kreutz group of comets, which are presumed to have come from a single parent object and all of the group follow a similar orbital path. It predicts that the comet will pass a mere 180,000 kilometers from the solar surface during its perihelion passage on December 16, 2011.
