Thursday May 9 to Thursday May 16


The First Quarter Moon is Wednesday, May 15.  Comet 12P Pons-Brooks is now visible when the sky is fully dark but is still a binocular only object. The comet will progressively climb higher and is near the iconic Orion constellation. In the morning the lineup of Saturn, Mars and Mercury makes for nice viewing.

Evening
sky on Thursday, May 9 as seen from Adelaide at 18:52 ACST (90
minutes after sunset, click to embiggen). Comet 12P is below Orion close to the star nu Eridanus in the constellation of the river.

While the comet is a modestly bright magnitude 5, despite now being visible when the sky is fully dark, you will still need binoculars. Over the week the comet will climb towards Orion and into darker skies, but becomes dimmer as it rises. Updated spotters charts are here.

Similar views will be seen from the rest of Australia at the equivalent local time (90 minutes after sunset).

Whole sky on Saturday, May 11 as seen from Adelaide at 18:51 ACST, 90 minutes after sunset (click

Canopus and the Southern Cross are a wealth of binocular objects to
discover. This is a good time to see fainter clusters.
