Meteors are a pleasant staring at box - they don't require a telescope, they usually may be visible on any transparent evening of the 12 months, even in vibrant twilight. It used to be the sight of a unmarried meteor that encouraged David Levy to enter astronomy, and during this e-book he encourages readers to move outdoor and witness those very good occasions for themselves. This publication is a step by step advisor to staring at meteors and meteor showers. Any precious technology is defined easily and in basically comprehensible phrases. it is a ideal advent to watching meteors, and is perfect for either professional and budding astronomers.

If, on the other hand, you are observing from a quiet place out of earshot of others, relax, have fun, and enjoy the sweeping show of the sky. Telescopic meteors and fireballs Telescopic meteor showers are showers whose average brightness is usually four or fainter. The June Bootids is one such shower, its meteors averaging about the ﬁfth magnitude. The Alpha Lyrids of July is another, although it also produces a few naked eye meteors. Through binoculars or a telescope some observers have reported counts of over 10 per hour.
Using a report form If you want to be more ambitious and use the IGY report form, here is how to proceed. With this extra effort, you will gain information about the shower rates per unit of time, how many meteors (shower vs. non-shower) appeared, and other interesting information about the shower. ” But how accurately the appearance of a meteor should be timed is a matter of hot debate, and the range of desired accuracy is large. When the International Halley Watch was accepting meteor shower reports, its required accuracy was only one hour for their hourly count statistics; they simply wanted to know the number of meteors seen in your hour of observing.
Bright meteors often leave trains, which are ionized high clouds in the path of the meteor. Trains usually last no more than a few seconds, but occasionally they can last for several minutes. It is deﬁnitely worth writing down when a meteor leaves a train. Sometimes a train is the only way to see a meteor. My own comet hunting has occasionally been interrupted by a bright ﬂash, but when I look around, all I see is a faint, long cloud that, over the next few seconds or minutes, changes shape and fades.
