Infographic: The Astronomy Highlights of Autumn 2019

September 2 2019, Marcus Schenk

 

In the next three months from September to November there are once again some great observing opportunities that we should not miss. A special event is fast approaching: the very rare transit of Mercury across the Sun. But there are also other smaller events to be seen.

The new astronomical infographic “Astronomy Highlights in Autumn 2019” offers you a quick graphical overview. This will keep you up to date and let you know what is happening in the sky.

September:

September 1: Alpha Aurigids

The Alpha Aurigids are a fast meteor shower moving at a speed of 65 km/s, which originated from the comet Kiess C/1911. At their peak on September 1, around six meteors per hour are visible. The radiant, that is the place from which the meteors appear to originate, lies in the Auriga constellation below the Capella star.

September 6: The Moon meets Jupiter

At a distance of just under 5° the Moon is approaching Jupiter this evening. Already at dusk we see them as bright objects that are close to one another.

September 8: The Moon meets Saturn

While the Moon was seen near Jupiter two days ago, it is today visiting the ringed planet Saturn. Both celestial bodies approach one another at a distance of 1.5°.

September 9: The Moon’s Golden Handle

This evening we experience the Moon’s golden handle. A fairly rare event that can only be seen during a Moon phase of 83%. Then we discover a closed semicircle of golden light on the dark side of the Moon’s boundary between light and shadow. The reason for this: we are looking at the Mare Imbrium and the Sinus Iridum crater, which is surrounded by the Montes Jura range. While the crater is still lying in darkness, the Sun rises over the mountain peaks and we see the famous handle.

September 10: Neptune in opposition

Neptune is one of the outlying gas giants of our solar system. At a distance of 4.5 billion kilometres, it takes 165 years to orbit the Sun. Its light is en route for 4 hours and 10 minutes before it arrives at the Earth. During its opposition it is particularly easy to see in Aquarius. At 1am it reaches its highest point, around 36° above the horizon.

September 20: The Moon meets Aldebaran

The waning Moon, which is 72% illuminated, meets Aldebaran, the main star of Taurus, during the night of September 20. Aldebaran is a red giant, a star that has reached the last phase of its life. It shines 150 times brighter than the Sun and is so large that if it were to take the place of the Sun it would reach as far as Mercury.

October

October 3: The Moon meets Jupiter

An especially pretty sight awaits us this evening: the Moon meets up with bright Jupiter. This impressive conjunction is worth observing, especially as dusk begins.

October 5: The Moon meets Saturn

In the early evening in Sagittarius, just above the horizon, today you can see a conjunction of Saturn and the Moon.

October 9: The October Draconids

Shooting stars appear to be falling from the Draco constellation on October 9: this is the Draconids meteor shower. As they dart across the sky they are a fascinating spectacle, even for amateur astronomers. The radiant is located near the star Draconis. Draco is a circumpolar constellation, therefore the radiant lies at an optimal visible altitude in the evening sky.

October 12: Amphitrite in opposition

Amphitrite is a sea goddess in Greek mythology and is married to Poseidon. In the sky, however, Amphitrite is an asteroid of the main asteroid belt, which is now in opposition. It is 211 million kilometres away from Earth. It is currently in Pisces below the Andromeda constellation.

October 17: The Moon meets the Hyades

The Hyades open star cluster is very old at 600 million years and forms a V-shape with its brightest stars. The moon visits the cluster tonight. By the way: the Aldebaran star does not belong to the Hyades.

October 20: Mercury’s greatest eastern elongation

Mercury is at its greatest elongation angle of 24°, but we still don’t see it in the evening sky.

October 21: Orionids

The Orionids are a smaller meteor shower with about 25 meteors per hour. The radiant is located in the Orion constellation near the Betelgeuse star. Although you can watch the shooting stars all month long, the peak is seen between October 20 and 21.

October 23: The Moon meets Regulus

Today the slender crescent moon can be found at a distance of around 10 degrees from Regulus, the main star in Leo.

October 28: Uranus in opposition

Now there is another opportunity to take a look at distant Uranus: it can be seen all night during its opposition. With a brightness of 5.6 mag. you can see it with binoculars alone, but is only recognisable as a planet using a telescope. You will find it in the Aries constellation. To find it draw a line from the bright β Ari star to the just 4.3 mag. dim star ξ1 Cet in the Cetus constellation. At the start of the last third of the line to ξ1 Cet, you will find the planet.

October 31: The Moon meets Jupiter

Tonight we see a slender and only 15% illuminated crescent moon directly next to Jupiter.

November

November 2: The Moon meets Saturn and Jupiter

This evening we see a nice conjunction of the Moon, Saturn and Jupiter on the southwestern horizon.

November 6: Taurids

The Taurids are a two-part meteor shower with just 10 meteors per hour expected. What is much more interesting is that some bright fireballs may also be visible.

November 11: Mercury Transit

It only happens every 13 years: Mercury passes across the solar disc and we can follow this transit live through a telescope. It starts at 13:35 CET, the 2nd contact is at 13:37 CET, the middle at 16:19 CET, the 3rd contact 19:02 CET, finishing at 19:04 CET. Unfortunately we can only observe half of the transit because the sun has already disappeared over the horizon. Attention! Always use a suitable solar filter for your observation! Never observe the sun without one! Observation without a special solar filter is dangerous and will lead to severe retinal damage. Let us advise you.

November 14: Asteroid Vesta in Opposition

The asteroid Vesta belongs to the main asteroid belt and was one of the first bodies of its kind to be discovered. After Pallas, it is one of the largest asteroids with a diameter of 516 kilometres. On November 14 Vesta reaches a brightness of 6.5 mag. and so you can find and observe it with any telescope. It is currently in the Cetus constellation. You can find it relatively easily by extending a line from o Tau (in Taurus) about 2 degrees to the west. A star atlas is useful here.

November 17: Leonids

On November 17 the Leonids reach their peak. In addition to the Perseids, they are among to the most famous shooting stars. There have been years when these meteors fell like raindrops from the sky. This usually happens every 33 years when the Earth collides with the Leonid cloud.

In normal years, the shower reaches a peak of no more than 20 meteors per hour. This year the rate of occurrence is a little lower, with 15 meteors per hour expected.

November 24: Jupiter meets Venus and the Moon meets Mars

In the last days of November there are two conjunctions: the Moon and Mars, and Jupiter and Venus.

In the early morning of the 24th we see a delicate crescent moon, Mars and, a little further below, Mercury. Then the following evening, in the very early twilight, there is a beautiful view of Jupiter and Venus.

November 28: Mercury’s greatest western elongation

Mercury reaches the best morning visibility of the year from November 28 at its greatest western elongation, now it has an angular separation from the Sun of 20 degrees. Through a telescope Mercury appears half-illuminated.

Infographic: The Astronomy Highlights of Summer 2019

June 3 2019, Marcus Schenk

Summer and warm temperatures: now all those who were hibernating in the winter can venture outside for a glimpse at the stars. But unfortunately it also gets darker later and then, as if turbocharged, light again just a few hours later. So you need to make good use of the hours of darkness, because when the summer Milky Way stretches across the sky there’s so much to discover.

The new astronomical infographic “Highlights in the Summer Sky” shows you at a glance what is happening in the sky in the months from June to August. Also included: a short description of the events.

June 5: The Moon meets Mars

Just two days after the new Moon, the slender crescent Moon stands seemingly fragile as dusk falls in the evening sky. Inconspicuous at around 2.5 degrees further to the right you will find the 1.7 magnitude bright Mars.

June 10: Jupiter in Opposition

You can now observe the largest planet in the solar system all night. Jupiter is in opposition this month, so this is the best time for observations. The gas giant reaches a magnitude of 2.6 and is 640 million kilometers away. As night falls the planet emerges above the horizon in the southeast, later it quickly becomes brighter and gets easier to see. At around 1:15 CEST it reaches the meridian and is particularly good to see.

June 18: Mercury Half Phase

Mercury reaches dichotomy, that is, a phase in which it is half-lit. Like the Moon or Venus, Mercury displays different phases.

June 18: Mercury meets Mars

A very beautiful event takes place shortly after the middle of the month: a close encounter between Mercury and Mars. Our innermost planet passes Mars at a distance of just half a lunar diameter, 13 arc minutes. This event takes place just above the western horizon at around 21:30 CEST. To observe these two it’s best to use binoculars.

June 19: The Moon meets Saturn

This configuration takes place in the second half of the night and can be followed until sunrise. Our Moon and the ringed planet approach each other with a minimal separation of about 2°50′.

June 24: Mercury’s greatest eastern elongation

Mercury gradually leaves the evening sky but it can still be seen, and can initially be found with the naked eye. From the second half of the month it becomes more difficult to find since it is so faint, and you’ll need the help of binoculars. It reaches its greatest angular distance of 25° from the Sun on 24 June. It reveals an almost half-lit sliver to us with a size of 8 arcseconds..  You can find Mercury with a good pair of binoculars from around 22:00 CEST.

July 2: Chile Total Solar Eclipse

In South America the Sun will grow dark. The eclipse’s shadow comes from the direction of the Pacific Ocean and stretches across Chile with a totality duration of 2:30 minutes. Later, the shadow moves onwards over Argentina. The Sun will be relatively low during this eclipse which will enable beautiful shots of the eclipsed sun against the landscape.

July 5: Noctilucent Clouds

Now in June you will be able to see them: noctilucent clouds. When the summer Sun is between 6° and 16° below the horizon it sometimes illuminates extremely thin clouds of ice crystals that are at an altitude of about 80 kilometres. These clouds are indeed so high that they are in the mesosphere part of our atmosphere. For us it is long since nightfall, but these clouds catch a little sunlight and we see bluish white clouds illuminated, which are invisible by daylight.

July 9: Saturn in Opposition

At present we have the problem that, due to the Sun’s ecliptic, many planets are far to the south and so are not high enough in the sky to be visible. Because of this we inevitably face a struggle with air turbulence. Despite this, Saturn still is worth observing, even if it only climbs to a height of 18°. On July 9 it reaches its opposition and shines brightly in the sky with a magnitude of 0.1. It is competing with the brightest stars but we can recognise it by its yellowish colouring and a faint glow that differs from the flickering of the stars. Because of this you can find it straight away and you can easily capture it with a small telescope. Its rings appear tilted at 24° and we are looking from the north at the ring system in which we can easily recognise the Cassini Division.

July 14: Pluto in Opposition

Pluto is a hard-to-see dwarf planet that used to be classified as a planet, and can barely be distinguished from a star – at least if you don’t have a map at hand. Even so, it’s worth taking a look at this outpost of the solar system with a larger telescope. GoTo coordinates: RA: 19h33m40s, DEC: -22° 07′.

July 16: Partial Lunar Eclipse

In January we had to view this in the cold, but not today. We can observe this partial lunar eclipse in warm temperatures and at a reasonable time. It gets interesting for us at 22:01 CEST, at which point the Moon enters the umbra of the Earth. Over the course of the evening it will become up to 66% obscured before the umbra moves away again and eventually disappears at 1:00 CEST.

July 20: Moon Landing 50th Anniversary

50 years ago today the whole world looked towards the Moon: to three astronauts, pioneers of humanity, who dared to set out on the greatest adventure. Apollo 11 flew to the Moon and Neil Armstrong became the first person to set foot on a foreign celestial body. Let us celebrate this event, remember it, and look again today towards the Moon, perhaps even to the Sea of Tranquility, the landing site of this daring mission.

July 29: The Delta Aquariids

A small meteor shower in Aquarius which we can best observe after midnight. The Earth passes through trails of small dust particles which burn up when entering the atmosphere and become streaks of light. We can expect to see 20-25 meteors per hour provided we find a dark place for our observation.

August 9: The Moon meets Jupiter

Similar to in July, the Moon and Jupiter meet again today. When it gets dark they stand dominant and bright in the sky above the southern horizon.

August 10: Mercury’s greatest western elongation

Now Mercury reaches its greatest angular distance of 19° from the Sun. Whilst before it was an object of the evening skies, for around 10 days from today we can discover it in the morning sky. On August 10 Mercury rises at 4:30 CEST, it then disappears into the haze, then it rises higher and we have a good chance of seeing it in the sky around 4:50 CEST.

August 12: The Moon meets Saturn

We have almost full Moon, so the sky is brightly lit, but Saturn shines clearly visibly and just 5° from the Moon. If our gaze wanders a little more to the right and a few degrees higher, we will also find Jupiter.

August 12: The Perseids

Every year we look forward to the most beautiful shooting stars of the year: the Perseids. In the morning of August 12 the meteor shower reaches its peak. Up to 100 shooting stars per hour rain down, thundering through our atmosphere at incredible speeds of around 216,000 km/h. The peak will be reached between 22:00 CEST and 4:00 CEST. Unfortunately this year the almost full, and far too bright, Moon will disrupt the display so that we are likely to only be able to observe the very brightest shooting stars. It’s best to find a spot away from the direct glare of the Moon. We have the comet 109P/Swift-Tuttle to thank for this meteor shower, which lost part of its mass on its orbit around the Sun. Whenever the Earth crosses the orbit of the original comet in August, the Perseids shoot across our corner of the sky.

August 23: Occultation of the Hyades by the Moon

Unfortunately, it’s not until the early hours that we can observe an interesting occultation of the star 61 Tau by the Moon. Such occultations of the Hyades star cluster are particularly interesting because it contains many bright stars and we can sometimes even see multiple occultations. Around 4:40 CEST the Moon approaches from its illuminated side and snuffs out the 3.7 magnitude bright star. The star remains hidden behind the Moon for a little more than an hour. At 6:00 CEST, as if out of nowhere, it suddenly reappears. Important: point your telescope at the Moon a few minutes beforehand to ensure you don’t get the timing wrong.

August 27: Occultation of Delta Geminorum (Wasat) by the Moon

The Moon has migrated to the next constellation in recent days and is about to enter its new Moon phase. Before sunrise, it occults a really bright star: this time the double star 55 Gem in the constellation Gemini. The Moon, at this stage just a thin sickle-shape in the sky, approaches from its illuminated side. At 5:50 CEST the time has come: the star disappears behind the Moon and reappears nearly an hour later at 6:40 CEST. But by then the Sun has long since risen, the sky is bright and so the reappearance is difficult to observe with a telescope.
