In mid-November, spectacular meteors will streak through the night sky as the Leonid meteor shower hits Earth once again. This annual meteor shower is responsible for some of the most intense meteor storms in history. The 1966 Leonids were certainly the greatest meteor shower in recorded history as it produced rates as high as 40 meteors per SECOND! We celebrate this year the 50th anniversary of this unforgettable event.

The Leonids are associated with the comet Tempel–Tuttle (55P). Earth moves through the meteoroid stream of particles left from the passages of this comet every year in November. The Leonids are a fast moving stream which encounter the path of Earth and impact at 72 km/s. Larger Leonids which are about 10 mm across have a mass of half a gram and are known for generating very bright meteors. An annual Leonid shower may deposit 12 or 13 tons of particles across the entire planet. The Leonids get their name from the location of their radiant in the constellation Leo: the meteors appear to radiate from that point in the sky.

The Leonids had been relatively quiet for 100 years between 1866 and 1966. Astronomers predicted an intense display in 1899 and when they failed to impress that year the public scorned astronomers for many years. It was not until the bright comets of 1910 did the public look again favorably on astronomers.

The sky was raining meteors

In Journal of the British Astronomical Association, Vol. 77, pp.89-93, Denis Milon, Association of Lunar and Planetary Observers remembers:

“The sky literally began to rain shooting stars. Everywhere we turned we saw them. We excitedly figured hourlys rates from our counts and wondered how this would compare with the great showers of the past. It was obvious to us that this type of shower would terrigy the ignorant, not to mention effects upon astrologers!”

James W. Young was one of the few people who photographed this event. Young observed the shower from the Table Mountain Observatory, operated by the Jet Propulsion Laboratory (JPL), located just west of the town of Wrightwood, California at an elevation of 7500 feet. Young says:

It is estimated that the average person sees 4 ‘fireballs’ in their lifetime. The above ‘fireball’ cast heavy shadows for about 6 seconds, and the luminous train left by it lasted about 10-12 minutes. We photographed over a thousand meteors in 90 minutes.

Alan Duniven witnessed the storm from Texas:

My dad, mother, and at least two other brothers and I witnessed the spectacular event from the Texas
Panhandle, near McLean. We apparently came out at about the peak time as approximately 50 meteors per second were radiating from one area of the sky at a very high angle. It appeared much like a sparkler from the 4th of July except there was a small vacant hole from which they radiated out.

Next one?

In “Leonid predictions for the period 2001-2100“, WGN, Journal of the International Meteor Organization, 35 (1): 5–12, Mikhail Maslov explains that a number of outbursts are expected in 2034 and 2035. It will be quite strong, and considering the proximity of comet Tempel–Tuttle, activity at 18:00UT on November 17th should reach a ZHR (the rate a meteor shower would produce if seen by an observer with a clear, dark sky, and with the radiant at the zenith) of 40-50 meteors. Maslov predicts a ZHR of 150-250 meteors on november 18th this year and a ZHR of 300-400 meteors on november 19th. For comparison, the ZHR for this year and next year should be around 10…

“Night of your birth. Thirty-three. The Leonids they were called. God how the stars did fall. I looked for blackness, holes in the heavens. The Dipper stove.” – From: Cormac Mc Carthy, “Blood Meridian” (1985).

    I was born in Clearwater Florida July 26th, 1966 underneath an orange sky. My life was inextricably ricocheted on a blessed trajectory. Happy anniversary Leonie showers we are soon to be 51.

    I witnessed the 1966 event from Excelsior, Minnesota. I woke up in the early morning hours, maybe 2 o’clock AM. I just happened to look out the window and saw meteors showering down, but my first thought in my sleepy 11 year old mind was that we were being invaded by flying saucers. I woke up my younger brother Don in the bunk bed above me and told him to wake up because there were flying saucers coming down from the sky. It didn’t take too long before we realized this was not men from Mars. Amazing that we didn’t know this was coming, but I randomly awoke to see it. I saw some of them appear to come down right in my neighborhood. One against the roof of a neighbors house. Then one right in my back yard, which I found the next day and kept for many years.

    Amazing. I hope this year’s a good one. I was born 7-26-66 but was the Leonid meteor shower in Nov?

    My mom reported seeing shooting stars that appeared to be going back up into the sky around this same time (1960s). She says she was at her grandparents house in Mariposa, California. Would this meteor shower give the appearance that the stars were going back up to the sky?

      Tina and All,
      As seen from the surface of the earth, meteors can travel in any direction including upwards. Of course they are not really traveling upwards as that is just our perspective as seen from the ground.

    I was born in a small town in the west Texas panhandle 11-17-66. My mom always told me a beautiful story of when I was born it was RAINING STARS. She said it was both brilliant and beautiful, while at the same time frightening for everyone who was witnessing the event. She described it as a dome and stars were coming down like brilliant rain. She said many thought the world was ending. I looked it up much later and learned there was a tremendous meteor shower called the Leonids that night. I love and cherish this story. I have been fascinated by stars and space my whole life.
