The autumn (or fall) Lyrids shower has historical resonances

It's a long three months for sky watchers in the southern hemisphere, was the height of the summer cutting down on transmission time. As Autumn (autumn) is, we are closer to one of the oldest observed meteor showers on Earth - the Lyrids shower.

As this shower (like all meteor showers, a remnant of a comet - Comet Thatcher said, in this case) comes from something more than theEcliptic, it is visible on the northern horizon to us, with a peak that occurs at some point between 19 April 22, with some meteors come by as early as the 12th and some come as late as May 3rd.

This shower can not be bound to a single comet remnants, or the remnants of comets may have an odd orbit, about every 60 years thereafter, the Lyrids on a huge show, going 60-10 meteors per hour up to a hundred or more per hour. The most spectacular meteor showerEvent in the modern history of astronomy seems to be a Lyrids shower in April 1803, which in the northern hemisphere had so many meteors on the east coast of the United States that it intended to be (in some parts) that have the word was a coming end. Many drawings of the night sky and pictures of the event exist, including at the Meteors sky enough to cause multiple shadows of people standing on the roadway.

Because of the times of the pericyclic Lyrids shower, and hisperiodic outbreaks, mathematical calculations of the orbital elements are tricky. The "about every 60 years" rule for the Lyrids was used to, it is likely to record events as far back as 638 BC, the oldest astronomical event recorded retreat on record.

One of the interesting confluence of the Lyrids is that they are the remains of more than a comet may have had; comet Thatcher has a 417 years orbital period and the peak of the Lyrids stream approximately every 60 years ... and superPeaks, which we do not have long enough to determine their baseline frequency. explosively - - to do with an eccentric with a track longer than the other, and a periodic confluence of two major elements bursts Lyrids This points to the possible collision with a comet or calving, where the comet nucleus produced in two parts.

While we're pretty sure this is not a "once very 60 years," burst (the last was in 1982, and we are not for any other reasonto about 2042), Lyrids are a pretty reliable meteor shower observations, although with the time of year, you will want to up by 2 to 4 clock in the morning to live to see it from where you.
