The Sky This Week - Thursday September 13 to Thursday September 20
The First Quarter Moon is Monday, September 17. 4 bright unaided eye
planets can be seen in the evening sky and are visited by the Moon in turn this week. Venus is high in the early
evening sky and is moving towards Jupiter. The crescent Moon is close to Venus on the 13th, and Jupiter on the 14th.
Jupiter is past opposition, but is still big and bright in telescopes.
Saturn and Mars are visible in the evening skies. Saturn is close to the Moon on the 17th and Mars is close to the Moon on the 20th. Comet 21P may be seen in binoculars in the morning
The First Quarter Moon is Monday, September 17. The Moon is at Apogee, when it is furthest Earth, on the 20th.
Evening twilight sky on Thursday September 13 looking west as seen from
Adelaide
at 19:29 ACST (90 minutes after sunset). Venus is high above the horizon
and is close to the crescent Moon as it heads towards Jupiter. Jupiter is now high in the western sky as
well.
The insets shows simulated telescopic views of Venus as seen with a 5mm telescopic eyepiece and Jupiter on Thursday September 13.
Similar views will be seen throughout Australia at the equivalent local time (90 minutes after sunset, click to embiggen).
Brilliant Venus is visible high in the evening until well after full dark. Venus is visible to the unaided eye from before sunset, easy to see shortly after sunset and can viewed well after 90 minutes after sunset. During the week Venus heads towards Jupiter. Venus is close to the crescent Moon on the 13th.
Whole sky view of the evening sky on Friday September 14 as seen from
Adelaide
at 19:30 ACST (90 minutes after sunset). Four bright
planets are visible in the evening sky.
Similar views will be seen throughout Australia at the equivalent local time (just after 90 minutes after sunset, click to embiggen).
Evening
sky on Monday September 17 looking north as seen from Adelaide
at 19:31 ACST (90 minutes after sunset). Saturn and Mars are
clearly visible. The Moon is close to Saturn on the 15th. The
insets are simulated telescopic views of Saturn and Mars as seen with a 5mm telescopic eyepiece.
Similar views will be seen throughout Australia at the equivalent local time (90 minutes after sunset, click to embiggen).
Location of comet 21P Giacobini-Zinner as seen from Adelaide at
astronomical twilight (4:55 am, 90 minutes before sunrise) looking
north-east on Saturday 15 September.
The location of the comet is marked with a red cross. Similar views will be seen elsewhere in Australia at the equivalent local time (90 minutes before sunrise,click to embiggen).
The comet will be visible as a fuzzy dot in binoculars.
Venus is readily visible above the horizon in the early evening. It is bright enough to be visible from just on sunset and to well past 90 minutes after sunset at full dark, when it is four hand-spans above the horizon. During the week Venus heads towards Jupiter. Venus is close to the crescent Moon on the 13th.
Mercury is deep in the twilight in the morning skies and very difficult to see.
Jupiter is high in the early evening sky above the western horizon. It was at Opposition on the May 9th, and is still visible most of the night. It is a good telescopic object in the early evening and is setting around 11:00 pm local time. This week Jupiter continues to move away from the bright star alpha Librae (Zubenelgenubi) and is close to the crescent Moon on the 14th.
Mars is in Capricornius and is readily seen in the evening. Mars was at opposition last month on July 27th, when it was biggest and brightest as seen from Earth. This was the best opposition since 2003. However Mars will remain bright and large in even small telescopes for some time. In a telescope you may see a few features as the huge dust storm sweeping the planet continues to subside. A guide to observing Mars at the time is at my Mars Opposition page. Mars is close to the Moon on the 20th.
Saturn is now high in the northern evening sky in the early evening, and is a good telescopic object in the mid to late evening sky. It was at opposition, when Saturn is biggest and brightest as seen from Earth, on June the 27th. It is within binocular range of the Trifid and Lagoon nebulae. With the waxing Moon close to Saturn on the 17th the nebulae are hard to see.
