Comet 12P Pons-Brooks may be visible above Jupiter at the beginning of the week and will progressively climb higher over the week. In the morning Mars and Saturn are high.Venus is barely visible low in the morning twilight below the pair. Mercury joins Venus late in the week and is closest on the 20th.

The First Quarter Moon is Tuesday, April 16.  The Moon is at apogee, when it is furthest from the Earth, on the 20th.

Evening sky on Sunday, April 21 as seen from Adelaide at 18:39 ACST (60 minutes after sunset, click to embiggen).   Jupiter is almost lost above the north-western horizon. Comet 12P is close to the pair of Xi and omicron Tau (the inset is the approximate binocular view of the trio).

While the comet is a reasonable bright magnitude 4, it is still not far from the horizon and will be difficult to see it through the horizon murk. You will definitely need binoculars. Over the week the comet will climb higher above the horizon murk and should be easily located in binoculars by sweeping up from Jupiter. Spotters charts are here.

Similar views will be seen from the rest of Australia at the equivalent local time (60 minutes after sunset).

Morning sky on Saturday, April 20 as seen from Adelaide at 06:03 ACST, (45 minutes before sunrise, click to embiggen). Mars and Saturn are pulling apart as Saturn climbs higher. Venus is now very low on the horizon and difficult to see. Mercury joins the lineup and is close to Venus on the 20th. You will need binoculars to see mercury.
