This phenomenon occurs at specific times during the year, although it may happen in much smaller numbers as well, known as sporadic meteors. In 1933 and 1946, the shower produced brief but intense meteor storms (more than 5,000 per hour); in 1998, it reached a rate of about 500 meteors an hour over eastern Europe.

Although the Draconids occur every October, it is usually difficult to know just how active each year's meteor shower will be. Reset your password. For this purpose more than 470 visual records of Lyrid meteors, observed at the Skalnaté Pleso Observatory over a period of four years, are analysed and converted to zenithal hourly rates. October 1946. Science 08 Nov 1946: Vol. [55] The Sigma Arietids, a class IV meteor shower, are visible from 12 to 19 October, with a maximum zenithal hourly rate of less than two meteors per hour on 19 October. 434-435 DOI: 10.1126/science.104.2706.434 The Draconid meteor shower produced awesome meteor displays in 1933 and 1946, with thousands of meteors per hour seen in those years. The Draconid meteor shower is expected to happen on Oct. 8 during night time, with varying number of meteors showing up. Once in a great while, the Draconid meteor shower overachieves, like it did in 1933 and 1946. Meteor showers can be seen in the night sky, appearing as glowing trails of light, which many people often refer to as falling or shooting stars. 104, Issue 2706, pp. The radar usedfor these observations was a stand- What Is a Meteor Shower? Anunusually rich meteor shower was expectedon9 October, duringthe passage ofthe earth throughtheorbitofthe Giacobini-Zinner Comet. A few meteors can be seen per hour or can appear in a mass of about hundreds of meteors. The observations weremadeat the Sterling, Virginia, Lab-oratory of the Bureau, where regular experiments in radio wave propagation are conducted. The most intense Draconid meteor showers in recent history occurred in 1933 and 1946 when thousands of meteors per hour were recorded as the Earth plowed through particularly dense streams of comet debris. [59]" The Draconid appearances are irregular; there are years when they don't show up at all. Title: The Meteor Shower of October 9, 1946 Authors: Cleminshaw, C. H. Journal: Publications of the Astronomical Society of the Pacific, Vol.

The correction factor cos y Z R with the exponent γ = 1.47 is used.
It is best viewed from the Northern Hemisphere. Spawned from Periodic Comet 21P/Giacobini-Zinner, the Draconid shower (also known as the "Giacobinids") produced two of the greatest meteor displays in the 20th century, in 1933 and 1946. The Draconids are best viewed after sunset in an area with a clear dark sky. The activity of the Lyrid meteor shower in the years 1945–1947 and 1952 is studied. Though often a rather quiet shower, the Draconids did produce some awesome meteor displays in 1933 and 1946, EarthSky's Bruce McClure said, when thousands of meteors per hour were seen. European observers saw over 600 meteors per hour in 2011. Until about midnight there was only occasional meteor activity and then suddenly about an hour later, the activity began to grow, and by, by 3 o’clock, 3 am in the morning, it was quite dramatic. This meteor shower produced 200-1000 meteors per hour in 1933 and 1946, although it is usually much quieter. Other meteor showers radiating from Aries include the October Delta Arietids, Daytime Epsilon Arietids, Daytime May Arietids, Sigma Arietids, Nu Arietids, and Beta Arietids. The October Draconids, in the past also unofficially known as the Giacobinids, are a meteor shower whose parent body is the periodic comet 21P/Giacobini-Zinner.They are named after the constellation Draco, where they seemingly come from.Almost all meteors which fall towards Earth ablate long before reaching its surface.
The Draconids meteor shower occurs every year in early October, usually peaking in the first or second week of the month when the Earth is passing through debris left from the comet 21p/Giacobini-Zinner.
