The Draconid bathe – additionally referred to as the Giacobinids – is an actual oddity, in that its radiant level stands highest within the sky as darkness falls. That’s why you’ll see extra Draconids within the night hours than within the morning hours after midnight.
Predicted peak: predicted* for October 9, 2023, at 7 UTC.
When to look at: The perfect time to look at the Draconids in 2023 is the night of October 8 by means of the wee hours of the morning on October 9. The waning crescent moon (23% illuminated) is not going to intervene with most Draconid meteors.
General length of bathe: October 8 by means of 9.
Radiant: Highest within the sky within the night hours. See chart above.
Nearest moon phase: Final quarter moon is 13:48 UTC on October 6. In 2023, a waning crescent moon will likely be seen on the mornings of October 8 and 9.
Anticipated meteors at peak, beneath ideally suited situations: Beneath a dark sky with no moon, you would possibly catch 10 Draconid meteors per hour.
Notice: The radiant level of the Draconids stands highest within the sky as darkness falls. That signifies that, not like many meteor showers, extra Draconids are more likely to fly within the night hours than within the morning hours after midnight. This bathe is often a sleeper, producing solely a handful of languid meteors per hour in most years. However be careful if the Dragon awakes! In uncommon situations, fiery Draco has been recognized to spew forth many lots of of meteors in a single hour. That risk retains many skywatchers outdoors – even in moonlight – throughout this bathe.
Be sure to watch in a dark sky

The Draconids’ dad or mum comet
From the late, great Don Machholz (1952-2022), who found 12 comets:
The Draconids meteor bathe’s dad or mum comet, the article chargeable for the dust we see burning up in our environment, is the small periodic comet 21P/Giacobini-Zinner. Michel Giacobini visually found this comet on December 20, 1900, within the night sky, from the Good Observatory in France. The comet was faint and within the southern a part of the constellation Aquarius. Giacobini was utilizing a 46-centimeter (18-inch diameter lens) refractor telescope, the biggest telescope for comet searching on the time. Although the comet is periodic – with a 6.6-year orbit across the sun – observers missed it at its subsequent return. Then, on October 23, 1913, Ernst Zinner of Germany found the comet whereas variable stars. This was his solely comet discovery.
Comet 21P/Giacobini-Zinner comes about as near the sun as does Earth. Then it ventures again simply previous the orbit of Jupiter earlier than returning 6.6 years later. The International Cometary Explorer visited it in September 1985, making it the primary comet to be visited by a space probe.
Draconid meteor storms
The particles from the comet is just not scattered uniformly round its orbit. A lot of it’s nonetheless bunched close to the comet. Due to this fact, when the comet comes again into our neighborhood, it might probably produce a spectacular meteor bathe, often known as a meteor storm: lots of and even 1000’s of meteors per hour. This occurred in 1933 and 1946, with a number of thousand meteors an hour. Within the years 1985, 1998 and 2018, it produced elevated counts however not meteor storms. European observers noticed over 600 meteors per hour in 2011.
The final perihelion of the comet was September 10, 2018. On that very same night time, Comet 21P/Giacobini-Zinner got here nearer to Earth than it had in 72 years. Consequently, the Draconids had an outburst in 2018. See photos of the comet because it swept safely previous.
As a result of this comet has an orbital interval of almost seven years, the following perihelion received’t come till 2025. So we’re not anticipating an outburst this yr. However, then, nobody actually is aware of for positive.
The place is the radiant level?
The radiant point for the Draconid meteor bathe is close to the celebrities Eltanin and Rastaban, within the head of the constellation Draco the Dragon within the northern sky. Its far-north location is why the Draconids are greatest considered from the Northern Hemisphere. See the 2 charts above.
The Draconids are greatest within the night, as a result of the winged Dragon, the bathe’s radiant level, flies highest within the October sky at dusk. As night time passes – regardless of the place you’re on Earth – the radiant level sinks decrease in your sky.
You don’t need to find Draco the Dragon to look at the Draconids. These meteors fly each which approach by means of the starry sky. However discovering Draco is enjoyable and comparatively simple. The 2 charts above present you two simple methods to search out it. You’ll be able to star-hop both from the Big Dipper or from the Summer Triangle.
Draconid meteor bathe has a wealthy historical past
Astronomers within the early twentieth century speculated that meteors and comets have been associated. So in fact they tried to hyperlink numerous comets to the spectacular showers of meteors that typically rain down in Earth’s sky.
Comet 21P/Giacobini-Zinner was a very tempting object about which to make predictions. Keep in mind, it returns each 6.6 years, and its closest level to the sun is about the identical as Earth’s distance.
And Comet Giacobini-Zinner didn’t disappoint the astronomers.
The connection between 21P/Giacobini-Zinner and its meteors – so studied and mentioned amongst skilled astronomers within the early twentieth century – in all probability explains why the Draconid meteor bathe typically goes by the identify Giacobinids.
For a style of historical past associated to this bathe, go to the Astronomy Summary Service from the Smithsonian and NASA. Discover a 1934 article referred to as The Meteors from Giacobini’s Comet by C.C. Wylie. It’s an account of the famed meteor storm of 1933.
Draconid meteor bathe from the Southern Hemisphere?
It’s doable to view the Draconids from the Southern Hemisphere. However in case you’re so far south that the radiant level within the constellation Draco doesn’t rise above your horizon, or rises solely briefly, you received’t catch many.
As seen from the Southern Hemisphere, you would need to be slightly near the equator as a way to see Draco’s stars. Suppose you reside in northern Australia – say Darwin, Northern Territory, Australia – which is at 12 degrees south latitude. In that case, you’d have the ability to see the celebrities Rastaban and Eltanin very near your north-northwestern horizon at dusk in early October (given an unobstructed northern horizon). These stars would set pretty early within the night. And so that you wouldn’t see the top of Draco once more till dusk the next night.
Why early night? It’s as a result of, regardless of the place you reside worldwide, the top of Draco reaches higher transit (highest level in your sky) at round 5 p.m. native time in early October.
Thus, from latitudes within the Southern Hemisphere – even these as far north as northern Australia – you’d have a really slender window for seeing meteors. If you happen to’re within the Southern Hemisphere, and also you’re actually eager to see a Draconid, strive wanting as quickly because it will get actually darkish on October 7 and eight. And don’t count on a lot.

Backside line: In 2023, the Draconid meteor bathe – additionally referred to as the Giacobinids – will in all probability produce probably the most meteors on the night of October 8 and thru the early hours of October 9.
