Perseids rain down on Earth
Summer in the northern hemisphere is a good time for sky observation. The weather is usually pleasant, many are on holiday and it is also pleasantly warm in the evening – as at present, for example. Now it fits like a fist to the eye that after the MoFi with Mars , the Perseids also rain their shiver on Earth.
Perseids are coming soon…
On the subject of lunar eclipse I have provided you with articles. Today I'll add some pictures, but then it's definitely about the Perseids.
Perseids, what is that?
Attention, now comes the part with which you decide every small talk for yourself, it follows clever knowledge about the Perseids from Wikipedia.
The first recorded observation of the Perseids took place about two millennia ago around 36 BC in China. After that, there were reports from Japan and Korea. In Europe, the first known observation dates back to 811. From 1762, the first known written tradition from the book Introduction a la Philosophie naturelle by the Dutch naturalist Pieter van Musschenbroeck comes that the increased August meteorite activity is an annually recurring event. He describes that after the summer heat , falling stars can be seen in Belgium and the Dutch cities of Leiden and Utrecht. In 1792, there is an article in the Pennsylvania National Gazette about increased meteorite activity on August 15. Literally it says: "in the month of August there are more meteors to be observed in the atmosphere, than at any other period of the year…." The English naturalist Thomas Forster writes in his book The Pocket Encyclopedia of Natural Phenomena for August 10, 1827: "Falling Stars and Meteors abound about this time of year." In 1835, the Belgian astronomer and statistician Adolphe Quetelet wrote a written account of a meteor shower in the constellation Perseus. He was the first astronomer to associate the radiant of the August meteor shower with the constellation Perseus. Since the appearance of the Perseids coincides with the feast of the martyr Lawrence on August 10, who suffered martyrdom on a glowing grate in 258, they are popularly called Lawrence's tears or tears of Lawrence.
Perseids, what when and where?
Quite unromantically one has to realize that the Perseids are waste. These shooting stars, known as wish fulfillers, are just dissolution products of comet 109P/Swift-Tuttle. Its orbit crosses the earth annually around August 12, so that during this time the Perseid showers also occur. From July 17 to August 24, the strongest activity of the Perseids can be observed. This year there is a new moon on the night of 12 to 13 August. The moon will be below the horizon all night, so the moon will not reflect any "disturbing" light from the sun. Again, the best viewing time is between 2:00 a.m. and 4:00 a.m., with the peak of over 100 Perseids per hour being reached at 6:00 a.m. The shower rises towards the north-northeast and then moves towards the east-northeast. Thus, the shower moves slightly below the astronomical north pole towards sunrise.
Capture Perseids in the picture
To see the spectacle with the naked eye is very nice, it is even better if you can show it to others by photographing the Perseids. It's basically quite simple. The exposure time may be long, because the burning tears of Laurentius produce a bright light and are very easy to recognize in a photo. It is important to expose for a long time. Here it makes sense to take many pictures of the same sky area with an exposure time of 30 seconds. With the ISO, you should pay attention to the results of the respective sensor. With my Olympus, an ISO 800 is sufficient and I use LiveComposite. I use the pleasant effect that star trails can be drawn. Here are some examples.
Perseids – what else is falling upon us?
Shooting stars are commonly regarded as an astronomical spectacle in summer. However, this is not the case, as the following table shows (source: Time & Date).
