The Sky This Week - Thursday September 20 to Thursday September 27
The Full Moon is Tuesday, September 25. 4 bright unaided eye
planets can be seen in the evening sky. Venus is high in the early
evening sky and is at its greats brightness on the 21st. Venus and Jupiter are at their closest on the 22nd.
Saturn and Mars are visible in the evening skies. The Moon is close to Mars on the 20th. Comet 21P may be seen in
binoculars in the morning
The Full Moon is Tuesday, September 25. The Earth is at Equinox, when day and night are of equal length, on the 23rd.
Evening twilight sky on Saturday September 22 looking west as seen from
Adelaide
at 19:36 ACST (90 minutes after sunset). Venus is high above the horizon and is at its closest to 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 on Saturday September 22 and Jupiter on Friday September 21, At this time Io and its shadow are transiting Jupiter. Venus is a clear crescent in small telescopes.
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. This week Venus is at its closest to Jupiter on the 22nd, and at its brightest on the 21st.
Whole sky view of the evening sky on Saturday September 22 as seen from
Adelaide
at 19:36 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 Thursday September 20 looking north as seen from Adelaide
at 19:32 ACST (90 minutes after sunset). Saturn and Mars are
clearly visible. The Moon is close to Mars on the 20th. 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 returns to the evening skies but is hard to see low on the horizon 15 minutes after sunset.
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 full Moon in the sky the nebulae are hard to see.

Seeing comet 21P Giacobini-Zinner from Australia in September 2018
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).
21P Giacobini-Zinner is a nice little binocular comet currently putting on a nice display in the Northern Hemisphere. It is currently cruising across the milky way, with a nice backdrop of nebulae and clusters to enhance the view.
Sadly for us in Australia it is currently too low to the horizon to see. However, by the 15th the comet is high enough to see above the horizon. It will have faded from its peak, but will still be easily visible. At this time it is close to the open cluster M35.
Printable Black and white map with the binolcar view of Comet 21P as seen from Adelaide at astronomical twilight (4:55 am, 90 minutes before sunrise). The large circle is the field of view of 10x50 binoculars. Note this is chart is in the same orientation with respect to the spotter chart above. Click to embiggen and print.
In binoculars the comet looks like a fuzzy dot. The tail is probably only realy visible in telescopes and photographs, and there is a green tint visible on colour images.
The comet is travelling against the backdrop of the milky way, and by the end of the month is within binocular distance of the cone nebula.

[Aurora Alert] Geomagnetic warning and Aurora Watch (10-11 September)
The SWS has issued a geomagnetic warning and aurora watch for 10-11 September
(UT) due to ongoing solar wind streams from a coronal hole. This anytime during
the UT day on the 10th, with activity extending out to the 11th. The SWS
predicts active conditions with the possibility of outbreaks of minor storms on
the 11th. It is not clear if the solar wind will impact during night time
hours, abut it would pay to be alert form twilight on the 11th..
If these geomagnetic events occur and result in aurora they could be seen from Tasmania weather permitting. The Moon is just past New and will not significantly interfere with seeing aurora. Be patient, as the activity may rise and fall of the magnetic polarity of the wind may fluctuate significantly.
This event is unlikely to be spectacular, but still worth a look as viewing conditions are good (the Full Moon aurora on August 26 was good for those with clear skies despite the Moonlight, as was very active despite initial predictions of not much hapening).
Dark sky sites have the best chance of seeing anything, and always allow around 5 minutes for your eyes to become dark adapted.
As always look to the south for shifting red/green glows, beams have been reported consistently over the last few aurora, as well as bright proton arcs and "picket fences". A double arc, blobs, and curtains were seen in Septembers aurora last despite the moonlight.
Here is the near-real time satellite view of the clouds http://satview.bom.gov.au/
Cloud cover predictions can be found at SkippySky.
A new aurora camera is being installed at Campania, Tasmania. A live feed of the images from this camera is still not available.
SUBJ: SWS GEOMAGNETIC DISTURBANCE WARNING 18/19
ISSUED AT 0031UT/10 SEPTEMBER 2018
BY THE AUSTRALIAN SPACE FORECAST CENTRE.
Geomagnetic activity is expected to increase to Active levels
due to the arrival of CIR and HSS associated with a recurrent
equatorial positive polarity coronal hole. A period of significant
southward Bz component could produce Minor Storm levels.
INCREASED GEOMAGNETIC ACTIVITY EXPECTED
DUE TO CORONAL HOLE HIGH SPEED WIND STREAM
FROM 10-11 SEPTEMBER 2018

and visible auroras during local nighttime hours at high latitudes
such as Tasmania. Aurora alerts will follow if significant geomagnetic
activity actually occurs.

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 moves away from the bright star Spica and heads towards Jupiter.
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).
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.
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. Now that the Moon has left the evening sky this will be an excellent sight in binoculars.

The ISS pass of Wedensday 22 August (2018)
 |  |
| International Space Station pass near Arcturus tonight, Wednesday 22 August at 19:24 ACST. This was a short pass, with the ISS disappearing into earth's shadow (not in the sequence, the image sequence finished before the ISS actually disappeared). 12 images fro my CANON IXUS, ASA 400 3 seconds exposure, stacked in DeepSky Stacker. click to embiggen | Animation of all 12 frames in stacked in ImageJ. Click to embiggen. |
I managed to get the first in the series of bright ISS passes tonight, a lovely one that faded into Earth's shadow nicely. Sadly I will miss the next two, including the close Venus pass, as I am taking Middle One to Occupational Therapy and a Chess Tournament respectively. Enjoy them for me folks.

When and what you will see is VERY location dependent, so you need to use either Heavens Above or CalSky
to get site specific predictions for your location, a small
difference in location can mean the difference between the ISS passing
over Venus or missing it completely.
As always, start looking several minutes before the pass is going to start to get
yourself oriented and your eyes dark adapted. Be patient, there may be
slight differences in the time of the ISS appearing due to orbit changes
not picked up by the predictions. Use the most recent prediction for
your site.
