Thursday September 1 to Thursday September 8

The First Quarter Moon is Sunday, September 4. Three bright classical planets in a line in the morning sky, Saturn, Jupiter, and Mars. Mars is between the red star Aldebaran and the Pleiades cluster at the beginning of the week.  Jupiter is now readily visible in the late evening sky below Saturn. Saturn is now past opposition, but will be worthwhile viewing for may weeks to come. The Moon is close to Saturn on the 8th. Mercury is still high in the evening twilight this week.

Seeing Vesta at Opposition (23 August 2022)

The North-east horizon as seen from Adelaide at 20:00 ACST (8:00 pm) showing the location of Vesta (click to embiggen) on Tuesday, August 23, when Vesta is at opposition and at its brightest.Similar views will be seen elsewhere in Australia at the equivalent local time.The approximate binocular view of Vesta and the four guide stars at 20:00 ACST (8:00 pm) on Tuesday, August 23.  The helix nebula is shown but will not be visible in binoculars(click to embiggen, similar views will be seen elsewhere at the equivalent local time).
Black and white horizon chart facing east suitable for printing showing the guide objects of 4 Vesta Saturn and Fomalhaut as seen from Adelaide at 22:00 ACDST. Similar views will be seen elsewhere in Australia at the equivalent local time. Use the charts above to orient yourself to get to the guide stars.Black and white binocular chart suitable for printing showing the movement of 4 Vesta over August. The large circle represents the field of view of 10x50 binoculars. Click to embiggen and print.  Use the horizon chart to the left for orientation first.

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 gets to magnitude 5.8 just over unaided eye visibility at dark sky sites. Not really visible from suburban skies, but it will be easily visible in binoculars and small telescopes.

This year on Tuesday, August 23 is a okay opposition of Vesta, when it will reach a magnitude of 5.8  at its brightest with reasonable guide stars. The next bright opposition is  May 2025 it will reach magnitude 5.6 with good guide stars.

This year Vesta has some reasonable signposts to it, just before and just after opposition Vesta is roughly between the bright planet Saturn and the bright star Fomalhaut. In binoculars if you star hop from Saturn to iota Aquarii (see binocular charts above), then about two binocular widths from iota Aquarii to 66 Aquarii (the next brightest star, also labelled as g1 Aqr in the stellarium chart), upsilon (υ) Aquarii will also be in the same field. Vesta is in the same binocular field as 66 and Upsilon (and then Upsilon and 47) Aquarii. Vesta is the brightest object aside from Upsilon, 66 and 47 Aqr and its movement from night to night easily seen.
 
Finding Vesta with the charts should be easy. Print them out and use with a red-light torch (or a standard torch with red cellophane over it) so as to not disturb your night vision.

The Full Moon interfered significantly early on earlier in the month, but now the skies are free from interference. Just before opposition, at opposition and several days after opposition Vesta is bright and easily seen. 17 August to 4 September may be best.

The Last Quarter Moon is Friday, August 19. Four bright classical planets in a line in the morning sky, Saturn, Jupiter, Mars, and Venus.  Mast is close to the Moon on the 19th - 20th. Venus is becoming harder to see in the twilight. Jupiter is now readily visible in the late evening sky below Saturn. Saturn was at opposition, when it is biggest and brightest as seen from Earth, last week, but will be worthwhile viewing for may weeks to come. Mercury is easier to see in the evening twilight. The asteroid Vesta is at opposition and (just) visible to the unaided eye.

Southern Skywatch August 2022 edition is now out!

Evening sky on Monday August 15 as seen from Adelaide at 22:00 am ACST. Saturn is at opposition, when it is biggest and brightest as seen from Earth. Saturn also forms a triangle with delta and gamma Capricornii. Jupiter is just above the horizon and is within binocular distance of the waning Moon. 

The insets are the telescopic views of Saturn and Jupiter at the same magnification at this time. 

 

Similar views will be seen from the rest of Australia at the equivalent local time. 

The August edition of Southern Skywatch is now up (sorry about the delay, life happened). The planetary action is in the morning and evening skies with four bright planets, Saturn, Jupiter, Mars, Venus, and Mercury in the morning sky. Saturn is at opposition, when it is biggest and brightest as seen from Earth, Jupiter clims higher in the evening sky and Mercury is at its best in the evening this month. The asteroid Vesta also reaches opposition and unaided eye brightness.

August 1-3; Mars and Uranus less than 2 degrees apart (in same binocular field). August 4; Mercury and bright star Regulus close. August 5; First Quarter Moon. August 11; perigee Moon. August 12; Full Moon. August 12; Saturn and Full Moon close. August 15; Saturn at opposition, when it is biggest and brightest as seen from Earth. August 15; the waning Moon close to Jupiter (1 degree). August 19; Last Quarter Moon. August 20; Mars close to waning moon. August 23; apogee Moon. August 23; Asteroid Vesta at opposition. August 26; the thin crescent Moon is beside Venus low in the twilight. August 27; New Moon. August 29; Mercury close to thin crescent Moon in evening twilight. August 30-31; Mars between Pleiades and the red star Aldebaran.

Mercury  is climbing higher in evening sky, and is at its best this month and until mid-September. It is low in the twilight half an hour after sunset in the first week of the month and get progressively higher. On August 4 it is close the bright star Regulus, It is furthest from the Sun on the 27th when Mercury is visible well after dark has truly fallen On August 29-30 the thin crescent Moon and Mercury are moderately close.

Venus continues to sink towards the horizon and by the end of the month Venus is lost in the twilight glow.

On the 26th Venus and the thin crescent Moon are close.

Mars is becoming brighter as it nears opposition, it is in an area devoid of bright stars so is readily identifiable. On August 22, Mars is 3° from the crescent Moon. The pair easily seen together in binoculars. On the 1 to 3rdst Mars and Uranus easily visible together in binoculars (closes on 1 August). On August 20th , Mars is 5 ° from the waning Moon. The pair just seen together in binoculars. From the 20th on Mars passes between the Pleiades and Hyades, an excellent morning sight, on the 30-31st Mars is directly between the Pleiades and the bright red star Aldebaran.

Jupiter climbs higher in the evening sky and is an good telescopic object in the late evening sky, although still best telescopically in the morning. On the 15th Jupiter is close to the waning Moon, with the pair in the same binocular field and Jupiter only 1° away.

Saturn is climbing higher in the evening sky but remains seen in the morning skies. Saturn is at opposition on the 15th, and is visible the whole night. Saturn will be high enough for good telescopic observation in the evening and early morning. Saturn forms a shallow triangle with delta and gamma Capricorn, becoming more elongated as the month wears on. On the 12th (morning 13th) the Full Moon is close to Saturn.
