Sun Scientists disappointed its weak activity in the past year. Told journalists officer Lebedev Physical Institute of RAS Sergey Bogachev, the current solar cycle activity lights close to the so-called "minimum Dalton."
"Solar activity is traditionally measured by the number of Wolf, which depends on the number of sunspots on the solar disk and the number of groups. This setting is fixed with the 1750's. In the mid XIX century, it was found that it varies with a period of 11 years, and with only beginning of the observations registered 23 such cycles "- quoted Bogacheva Read more [...]
Sun today congratulated the people of Earth beautiful and powerful release to happiness is not directed toward our planet. LPI seems a long time celebrating New Year and no outbreaks in this context does not see at all. NASA warns that this night Earth will undergo a rapid flow of highly-particles of ~ 450 km / s, causing geomagnetic storms.Category: Sun Read more [...]
According to official data, there had been no sun flares and geomagnetic storms there, but NASA's monitoring data indicate the opposite — in the morning on the Earth's magnetosphere has been strongly influenced.
Sun winked mankind December 22 - the day after it became clear that the end of the world according to the Mayan canceled. "Winks" our star appeared on the pictures, made orbiting Solar Dynamics Observatory of NASA."Winks" The sun was due to three spots on the surface caused by magnetic activity. Pictures spots resemble footage from the first science-fiction film "Journey to the Moon", says The Daily Mail. The photos are of practical value - they can learn much more about the processes taking place on the solar surface.
At NASA, commenting on photos, did not fail Read more [...]
American scientists Adrian Melott (University of Kansas in Lawrence) and his colleague Brian Thomas (Washburn University in Topeka) studied heavy duty solar flare that occurred in the 8th century AD. Traces hyperactivity our star were found in tree rings of Japanese cedar.
Solar flares occur regularly and are the explosive process of energy release. But not each of them rise to the level of the investigated American scientists solar storm. The task of the scientists had set a rough flash 774 years, more or less accurately calculate the amount of energy released by our star. To do this, Melott Read more [...]
According to FIAN happened today 2 flashes of class C. The photos can be seen by satellite, stereo a bright and very large luminous object traversing the area of capture camera. The sun emits a narrowly focused permanent emissions.
Supervspyshka the Sun in 774 AD, was several times more powerful than the previous record holder, "Carrington Event" of 1859, can destroy all electronic devices and power on Earth, say astronomers in the article published in the online library at Cornell University.On the sun periodically outbreaks - explosive episodes of energy in the form of visible light, heat, and X-rays. It is believed that the most powerful flare occurred in 1859 during the so-called "Carrington Event". During this powerful flash yottodzhouley stood out about 10 (10 to 25 degrees) of energy, which Read more [...]
Simple question - why NASA always closes squares something he did evil in the pictures from satellites SOHO and STEREO are laid out in open access? And does it even concealing editing. That's higher than a show piece of "art" by the censor NASA.What is the picture appeared on the solar surface of the site, prompting NASA to close it with the image of a square piece of the surface taken from another site?Here is the original photo:Here's another example of "architecture" of NASAAnd these images only for the year 2012 - hundreds.Why and what is closed?Category: Sun Read more [...]
According to NASA's active regions AR1633 and AR1635 are capable of producing flashes of class M and they gradually turn toward Earth. Today the sun was 5 flashes according to the LPI, the strongest of which reached class C4.1
Sun activity is maintained at a uniformly high level. According to FIAN today outbreaks have occurred, but the video from the STEREO satellites suggests otherwise. Although now schedule LPI activity is starting to show a surge in activity has reached the Class C and is still rising. Let's see what happens as a result of the class. In addition, it is worth noting the increased concentration of flying objects in the Solar space. SOHO satellites spotted one such object, the enormous size. If this comet, it is strange that her approach had not noticed before, or do not notice. I Read more [...]
NOAA forecasters estimate probability of polar geomagnetic storms on December 24 10% to 20%, as a result of recent outbreaks. Wave emission can reach the Earth on Christmas Eve and will cause magnetic storms and auroras. NASA well as reports that the fact that the violent outbursts do not happen does not mean that the solar activity is low, it is misleading.Even if the flash is not directed toward Earth, they still reach it from the rotation, as shown in the figure below.Active areas on the Sun become more and more restless.
Yesterday, several CME flew over the edge of the solar disk, and now Read more [...]
On a long voyage to the southern hemisphere, the sun is heading in the opposite direction. Monday, December 24, is the first day of increasing daylight. Its duration will increase by 1 minute and at a latitude of Moscow will be 7 days hours 00 minutes.Then it will go faster. During the last week of December, the length of the day increases by 5 minutes, and during January - 1 hour 30 minutes!January 11 at a latitude of Murmansk complete polar night.Category: Sun Read more [...]
Solar activity remains at a high level. According to official data on the Sun today LPI was 6 flashes of class C. Whether the claimed class of real emissions - a big issue, but in the absence of alternative data to be content with the declared official. At this point, based on the existing (incomplete), stereo satellite imagery, flash is not directed toward Earth, but are in the immediate vicinity.Category: Sun Read more [...]
Since we are now in the high activity original solar comets, scientists are waiting for new opportunities in the years to follow. Large comet should pass near the Sun November 28, 2013. Its size is about how a comet Hale-Bopp. The size of the comet Hale-Bopp over 35 kilometers in diameter ...In addition, I want to show the list of potentially dangerous asteroids to Earth according to NASA on December 22, 2012. Asteroid Date (UT) Miss Distance Size 2012 1 December 19 5,8 LD 22 m 2003 SD220 December 23 59,8 LD 1.8 km 1998 WT24 December 23 69,2 LD 1.1 km 2012 Read more [...]
Site "Survival in the wild nature", glad to see you. If you come to us, it means you want to get complete information about survival in a variety of extreme conditions, in emergency situations. Man, throughout the development, sought to preserve and protect themselves from the various negative factors surrounding it - cold, heat, hunger, dangerous animals and insects.
Site structure "Survival in the wild nature" is simple and logical, selecting a specific section, you will find information. You will find on our website recommendations and practical advice on survival, unique descriptions and pictures of animals and plants, turn-based scheme to trap wild animals, tests and reviews of travel gear, rare books on survival and wildlife. The site also has a large section devoted to video on survival survivalist-known professionals around the world.
The main theme of the site, "Survival in the wild nature" - is to be ready to be in the wild, and the ability to survive in extreme conditions.
The Survival in the wild nature - how correctly to behave, it having appeared in an emergency situation. Ability to find a way out from any situation: to kindle a fire, to put traps, to prepare food, to arrange dwelling and a lodging for the night; to learn to knit knots, to clear water, to be guided by districts, correctly to choose equipment, a knife.
