The north-western sky as seen from Brisbane at 9:59 AEST on Tuesday 3 November. The moon is obvious above the horizon, but you will need binoculars or a telescope to see Jupiter.  The left-hand inset shows the magnified view just as the occultation starts, and the right-hand view is the view as Jupiter comes out from behind the Moon.

The northern sky as seen from Perth at 6:46 AWST on Tuesday 3 November. The moon is obvious above the horizon, but you will need binoculars or a telescope to see Jupiter.  The left-hand inset shows the magnified view just as the occultation starts, and the right-hand view is the view as Jupiter comes out from behind the Moon.

WARNING! This daytime occultation occurs not far from the Sun and should be attempted by experienced observers only. The Moon will be 76 degrees (around 12 hand-spans) from the Sun. Exposure to the Sun through a telescope eye-piece can result in instant blindness. Any observation should be carried out with the sun blocked from view by a building or similar large, obscuring object with no possibility of the sun being accidentally observed.

On the morning of Tuesday 3 November Jupiter is occulted by waning Moon as seen from the most of Australia, Indonesia, Papua new Guinea  and New Zealand. However far north Queensland misses out. The Moon is just past last quarter and high in the north to northwest. It is an obvious signpost for where to look.  Jupiter will not be visible to the unaided eye, but in binoculars and telescopes Jupiter will be obvious close to the Moon. The times of disappearance and reappearance of Jupiter is in the table below. 

Most of Australia sees Jupiter's satellite Europa get occulted first, then Jupiter will take around 2 minutes to disappear behind the Moon. For Darwin and  Brisbane Jupiter will skim along the Moons surface as it exits from occultation. Caloundra sees the Moon graze Jupiter, every where in QLD above Caloundra on the coast and Cape York sees a very close approach, well worth watching.  

Telescopic view of Jupiter and its satellites just before the occultation. Europa leads the way.	Telescopic view of Jupiter and its satellites just after the occultation. Europa still leads the way and the other satellites will appear to "pop" out.

Start watching about half an hour before hand to get set up and familiar with the sky. This is a daytime occultation requiring a small telescope or binoculars and extreme caution and attention to Sun safety. 

My blog of the 2012 Daylight Jupiter Moon graze should give you a feel for what it will look like, and some photography hints. 

Jupiter and its satellites will appear to "wink out" as it goes behind the bright limb of the Moon, reappearance will be harder to see as you have to be looking just at the right moment.

The occultation occurs in the early morning with the Moon reasonably high above the north-western to northern horizon. The Moon just past last quarter and should be obvious, but you will still need extreme care with the sun. 

The Moon is a signpost to Jupiter which will only be visible in binoculars or telescopes. It is advisable to set up and practice on the Moon in the morning before the event, so you are familiar with your telescope set-up. Set up at least half an hour ahead of time so that you can be sure everything is working well and you can watch the entire event comfortably (trying to focus your telescope moments before the occultation will cause a lot of unnecessary stress). Jupiter will be clearly visible in a telescope or binoculars near the Moon. Again, the Sun will be close by, so only experienced observers who can block out the Sun should attempt this.

Morning sky as seen from Darwin facing north at 4:00 am ACST on 22 October (90 minutes before sunrise), the Orionid radiant is indicated with a starburst. Similar views will be seen elsewhere in Australia at an equivalent local time. Click to embiggen.	Morning sky as seen from Brisbane facing north at 3:44 am AEST on 22 October (90 minutes before sunrise), the Orionid radiant is indicated with a starburst. Similar views will be seen elsewhere in Australia at an equivalent local time. Click to embiggen.	Morning sky as seen from Adelaide facing north at 4:55 am ACDST on 22 October (90 minutes before sunrise), the Orionid radiant is indicated with a starburst. Similar views will be seen elsewhere in Australia at an equivalent local time. Click to embiggen.

The Orionids are a worthwhile shower that somewhat favours the Southern Hemisphere, normally best seen between 2-5 am, with the radiant, the point where meteors appear to originate from, being just under Betelgeuse, the bright red star in Orion. The maps above show the views from Darwin, Brisbane and Adelaide at astronomical twilight (90 minutes before sunrise). Similar views will be seen at the equivalent local time at similar latitudes (Adelaide stands in for Melbourne, Sydney and Perth).

If you draw an imaginary line between Procyon and Aldebaran, then drop another imaginary line from Betelgeuse to the horizon, the radiant is just next to the intersection of those two lines.

The Orionids are the debris from Halley's comet. The Orionids maximum is on October 21 UT (October 22 Australian time).

This year the waning Moon will significantly interfere with viewing in the early evening and the rates will be low. Once the moon sets around 4 am the rates will be better.

If you decide to get up, allow at least 5 minutes for your eyes to adjust, and be patient, it may be several minutes before you are rewarded with you first meteor, then a couple will come along in quick succession.

Choose a viewing spot where you can see a large swathe of sky without trees or buildings getting in the way, or with street-lights getting in your eyes. The darker the spot the better (but do be sensible, don't choose a spot in an insalubrious park for example). Look to the north-east, and the distinctive red star Betelgeuse below the saucepan will be easy to spot, forming a rough line with with bright Procyon,  Mars and Jupiter below and to the east of it. The meteors should originate just below Betelgeuse. However, let your eyes roam a bit to pick up meteors that begin their "burn" a fair distance from the radiant.

A lawn chair or something similar will make your observing comfortable (or a picnic rug spread on the ground and a nice pillow), and having a Thermos of hot coffee, tea or chocolate to swig while watching will increase your comfort. (Here's some hints on dark adaption of your eyes so you can see meteors better).

Venus in the twilight on Friday, October 16 as seen from Largs Pier at 20:08 ACST. Samsung S24, 5x Zoom, ISO 2000 1/33 sec exposure	Western sky on the evening of Saturday, October 17 as seen from Adelaide at 20:08 ACST (30 minutes after sunset, click to embiggen). Venus is just above the horizon and below Mercury. Venus is a clear thin "Crescent Moon" shape and is increasing in size. The shape is readily in 10x50 binoculars (although the brightness may make it hard to see due to internal lens reflections).

The planets seen thorough binoculars are generally disappointing, Jupiter is a clear oblate spheroid, although featureless, but you can see the bright sparks of its satellites shuttling around. Saturn is a featureless ellipse, where you cant distinguish the rings from the planets body (but is is clearly an elliptical shape much boarder than Jupiter).

But for the next few days you can easily see crescent Venus in 10x50 binoculars (and even to an extent in smaller binoculars).

The wire thin crescent shape is readily seen in 10x50 binoculars, although the brightness may make it hard to see due to internal lens reflections. Best seen close to twilight and with  a binocular stand or something to rest your arms on so the binoculars don't shake. 

You only have about 4 more days  until Venus disappears  into the twilight, but then by the 30th is is high enough above the eastern twilight horizon for the thin crescent to be seen in binoculars. 

So why not grab you binoculars and go have a look tonight?

North-Eastern horizon on the morning of Monday,  October 12 as seen from Adelaide at 5:11 ACDST (90 minutes before sunrise, click to embiggen). Mars is in the heart of the Beehive cluster (M44).

From Saturday 10 October to Tuesday 13 June, Mars crosses the Beehive cluster (M44) in the morning. Under dark skies this delightful open cluster looks like a faint nebulous patch, but binoculars or a telescope will reveal it's wonderful starry mass. 

While in principle seeing Mars in the heart of the beehive is possible with the unaided eye, this is far better seen with binoculars or a small telescope, On the 10^th Mars on on the outskirts of the cluster, and on the 11^th and 12^th Mars is in the heart of the cluster. Then on the 13^th it is on the outskirts again. The cluster fits neatly into medium power telescope eyepiece fields on the on the 11^th and 12^th, although it is close to the horizon (16° at astronomical twilight). On the days leading up to the crossing and a couple of days after, Mars and the cluster are in the same binocular field.

The view is best at Astronomical twilight, and hour and a half before sunrise, much later than this and the Beehive gets washed out by the encroaching twilight. Mars is not so bright that it will drown out the clusters dimmer stats, so this will be a nice opportunity for some astrophotography.

The Asteroid 4 Vesta is one of the iconic minor planets, and one of two orbited by the Dawn spacecraft. At favorable oppositions Vesta is bright enough to be seen with the unaided eye under dark sky conditions. This year it only gets to magnitude 6.5 making it binocular only. It will be easily visible in binoculars and small telescopes even under suburban skies.

This year Monday, October 12 is a reasonable opposition of Vesta, when it will reach a magnitude of 6.5 at its brightest with no Moon interference and few reasonable guide stars.
