With out a question of doubt, the term “meteor shower” is a misnomer. It creates a psychological image of shooting stars pouring out of the sky tackle water from a sprinkler, nonetheless that’s merely not the case.
On a conventional evening, below a clear, murky sky that that you just must count three or four meteors per hour. On particular nights, that count could also merely climb to 15, 25, 50 per hour or extra. That’s what astronomers call a “shower.” The mainstream media most continuously enlighten the usual public to ask one thing spectacular, nonetheless continuously most — envisioning the “sprinkler attain” — are left disappointed.
A meteor storm is one thing else. In such cases, meteors will seem at charges of a thousand or extra per hour and in a pair of rare cases, charges personal been ten and even a hundred times better than this!
How continuously develop meteor storms occur? Here we provide a list of a few of the ideal meteor shows relationship relieve to the slack 18th century.

November 12, 1799: Grateful headache
Were it not for a headache, this spectacular portray of Leonid meteors could possibly personal been disregarded altogether. It modified into as soon as Alexander von Humboldt — a author-scientist-explorer of enormous recognition within the 18th and 19th centuries who chronicled what came about.
He and his colleague, French botanist Aimé Bonpland, had been situated in Cumaná, Venezuela. On October 27, they’d an come across with a “Zambo,” a membership-wielding native who gave Bonpland a concussion.
At 2: 30 a.m. on November 12, no subject a level-headed aching head, Bonpland stepped outdoors to reap the advantages of the freshness of the air. It modified into as soon as then that he noticed basically the most phenomenal, radiant meteors rising out of the sky from the east and northeast. He woke up Humboldt who wrote that “there modified into as soon as not a gaggle within the heavens equal to three full moons which modified into as soon as not stuffed with bolides (exploding meteors) and falling stars.” The meteors left radiant traces that continuously lasted from seven to eight seconds.
Many of the shooting stars had a nucleus as massive as Jupiter, from which darted sparks of colourful light. The portray gradually ceased after four o’clock, even supposing some falling stars could level-headed be detected for fifteen minutes after sunrise.
April 20, 1803: An alarming downpour
Yet one more spectacular storm of meteors that could also merely personal been disregarded, had been it not for a fireplace terror. The Lyrid meteor shower — every so often a rich portray — switch alongside in an orbit that strongly resembles Comet Thatcher of 1861.
There are lots of ancient records of meteor shows believed to be Lyrids, critically in 687 B.C. and 15 B.C. in China, and A.D. 1136 in Korea when “many stars flew from the northeast.” However most definitely basically the most principal Lyrid shower came about in 1803, when townspeople in Richmond, Virginia, had been roused from their beds by a fireplace terror and had been ready to thought a with out a doubt rich portray between 1 and 3 o’clock. The meteors “gave the impact to plunge from each and every point within the heavens, in one of these style as to resemble a shower of sky rockets.”

November 13, 1833: Starry snow fall
Most continuously thought to be to be indubitably one of basically the most opulent showers on tale. Varied studies one day of the United States described stars falling “as thick as snow coming down in a snow storm” Estimates as excessive as 20 per 2d had been made. Many fell on their knees to pray; others feared the enviornment modified into as soon as ending. Church bells had been rung. Other folks crowded the streets, afraid to live at home.
Fully with the principle light did the flashes proceed away. Several observers noticed a sure pattern to their walk, radiating from some extent procedure the star Gamma Leonis within the constellation Leo in such numbers as to form the sky in that direction resemble an umbrella. Recognition of this point, called the exquisite, modified into as soon as indubitably one of basically the most indispensable astronomical discoveries of the nineteenth century. Beforehand, astronomers had regarded “shooting stars” as too trivial a phenomenon great of indispensable glance, nonetheless now they could also merely now not be not mighty. This very excellent portray marked the starting of meteor astronomy.
November 14, 1866: European wonder
By now, astronomers had found that comets and meteor showers had been related; these particles released by comets alongside their orbits had been encountered by the Earth upon crossing the comet’s orbit, establishing a portray of meteors.
The comet accountable for the Leonid meteors — Tempel-Tuttle — modified into as soon as found in December 1865 and orbits the solar about each and every 33 years. It modified into as soon as assumed that 33 years after their closing massive performance, yet one more spectacular Leonid point to would occur in 1866. And certainly, it did happen — nonetheless not for The US. This time, Europe saw the firestorm.
One observer from Eire later wrote, “It’d be not potential to snort what number of hundreds of meteors had been viewed, each and every indubitably one of which modified into as soon as intellectual sufficient to personal elicited a reward of admiration on any typical evening.” However other folks that saw the Leonids of 1833 and 1866 talked about that the 1866 meteors — even supposing beautiful — had been some distance corrupt to other folks that appeared in 1833.
November 14, 1867: Second time around
Yet one more main Leonid shower appeared, this time over the United States. The single observer price modified into as soon as most definitely 1,500 per hour. No longer as mighty as the outdated one year, nonetheless according to the U.S. Naval Observatory, it modified into as soon as “basically the most excellent viewed in this country for the reason that broad shower of 1833.”
November 27, 1872: Rain of fire
(opens in new tab)
Biela’s Comet, which appeared slack in 1845, had cut up in two since its closing appearance six and a half of years sooner than. The new twin comets traveled terminate together. When these comets returned in 1852, indubitably one of many pair modified into as soon as very shadowy.
The comets had been looked for again in 1858 and again in 1865 nonetheless had been below no circumstances viewed again. However in 1872, as the Earth passed terminate to the orbit of the comet, its dusty remnants started inserting Earth’s atmosphere. From Moncalieri, Italy, quickly after 8 p.m. native time, four observers described the meteors as such as “a true rain of fire,” with meteors exhibiting at a price of 4 per 2d. Others talked about the meteors had been falling at charges too an even different of to count. The meteors had been described as slower than the Leonids and with out a doubt faint. They gave the impact to emanate procedure a question on the sky where the constellations of Cassiopeia, Perseus and Andromeda converged, so that they grew to turn into diagnosed as the “Andromedids,” or for the reason that meteoroids had been shed by Biela’s Comet they are as soon as in a whereas known as “Bielids.”
November 27, 1885: Ultimate trains
Thirteen years after the meteor storm of 1872, the Andromedids made a return appearance, with Europe again favorably placed to thought them. One smartly-diagnosed British meteor observer commented that “meteors had been falling so thickly as the evening developed that it grew to turn into nearly not potential to enumerate them.”
Other respected observers stationed in Italy and France talked about the one observer price reached over 200 per minute. From Scotland came the tale that a large different of meteors “had excellent phosphorescent trains, which continued to glow for lots of seconds after the meteors themselves had vanished.”
October 9, 1933: Surprise shower
(opens in new tab)
A history-making meteor storm came about on this evening over Europe when the Earth passed thru the wake of periodic comet Giacobini-Zinner. This very excellent portray modified into as soon as surprising and caught most astronomers entirely off guard.
The Calm York Occasions reported that “A veritable rain of falling stars modified into as soon as viewed over your entire of France and Belgium between 7 and 9 o’clock,” including that “Residents of rural areas in Portugal, by dread, started praying; some villages timid.” From Eire, the meteors “fell as continuously as snowflakes,” with charges at one point of 20 per 2d. An observer from Malta recorded a height price of 480 per minute.
The meteors gave the impact to lunge from the head of the constellation of Draco the Dragon and had been known as “Draconid” meteors, even supposing others called them “Giacobinids” after their parent comet. They had been described as slack, in general faint and had been most continuously yellow.
October 9, 1946: Cosmic fireworks
Unlike in 1933, astronomers had been ready for the Draconids in 1946. Comet Giacobini-Zinner modified into as soon as relieve and each and every it and the Earth gave the impact precisely positioned for a replay. In spite of a full moon, skywatchers weren’t disappointed.
One correspondent for Sky & Telescope magazine wrote: “Three of us tried to withhold count (of the meteors), nonetheless after tallying 500 ceased enumeration. There modified into as soon as no quarter of the heavens that modified into as soon as untouched by the fireworks.” From Chicago, yet one more observer talked about that the brightest meteors outshone Venus at her finest, and showed colours of pink, orange, and green and can personal to even be adopted when their paths led within the relieve of wisps of clouds.
Hourly charges diversified widely from as low as 3,000 to as excessive as 10,000.
November 17, 1966: Support from the dead
The Leonids had been dead, they talked about. Indeed, they’d not produced a meteor storm since 1867. The first reason modified into as soon as that their source, Comet Tempel-Tuttle, made a terminate reach to Jupiter in 1898; the massive planet’s gravitational subject threw each and every the comet and its flow of meteoroids off song.
So, in successive Leonid cycles in 1899 and 1932 the expected rich Leonid shows did not look. We had been about ready to present up on the Leonids after they keep on a enticing portray in 1966. From Kitt High Observatory in Arizona, one observer talked about some fireballs left trains that lasted as much as 20 minutes. On the Jet Propulsion Laboratory’s Table Mountain Observatory in California, observers saw “a rain of meteors turn into a hail of meteors, lastly turning correct into a storm of meteors too an even different of to count.” On the height, estimates ranged anyplace from 10 to an very excellent 40 meteors per 2d!

November 18, 1999: Immediate and sweet
A dramatic fusillade of Leonids sprayed from the Sickle of Leo one day of the starry sky as viewed from the longitudes of Europe and the Middle East. The roughly hour-lengthy outburst peaked at a price of 1 or two meteors per 2d as viewed by any given individual. It modified into as soon as some distance in need of the massive Leonid storm of 1966, nonetheless it with out a doubt modified into as soon as an epochal spectacle nonetheless. This portray contained a excessive share of faint meteors and a relative absence of fireballs.
November 18, 2001: Twin peaks
A most distinctive setup as two Leonid peaks had been forecast. The first, as Earth encountered subject fabric shed by Comet Tempel-Tuttle in 1766 favored North and Central The US. Meteors came in bunches and clusters and had been somewhat intellectual with hourly charges as excessive as 1,300 recorded.
Then came a 2d height due to concentrations of subject fabric released by the comet in 1699 and 1866 which favored Australia and the Some distance East. That proved to be the extra intense outburst, with numbers peaking at around 4,200 per hour. And from Massachusetts to Manchuria, all americans modified into as soon as impressed by the an even different of fireballs that left lengthy-enduring trains lasting as much as lots of minutes.
November 19, 2002: A flick of the swap
All over again, a one year with two Leonid peaks. Observers likened each and every outburst to a swap being turned on and off — with out warning there had been loads of meteors after which impulsively, they had been all nonetheless long gone.
The first height favored Europe; corrected single observer counts indicated a price of about 2,300 per hour. The 2d height favored North The US where estimates indicated an hourly price of about 2,700. However additionally, one thing of a disappointment due to the presence of a intellectual full moon and a relative dearth of intellectual meteors.
