November 5 on the reverse side of the sun there was something akin to a crack.
Center for space weather forecasts (Space Weather Prediction Center) of the National Oceanic and Atmospheric Research U.S. (NOAA) has notified the sharp strengthening of activity in the current group of sunspots - 1121. The pictures, taken November 5 solar observatories SOHO and SDO X-ray, it appeared a giant crack. And on November 6 in this place there was a flash of X-ray. Experts have determined that it was the third power in the last 10 years. And the event is attributed to the class M 5,4.
In principle, these outbreaks are dangerous for the Earth. Are able to hurt themselves - the next class - X, which is 10 times more powerful....
Fortunately, the active region that produced the flash was visible for the first edge of the solar disk, and then - at the very edge of its. And the flow of hard X-rays were directed away from our planet. For this reason, we will not fall into the so-called coronal mass ejection - a plasma brand plucked from the depths of the light in those moments lasted until the X-ray flare.
The outbreak occurred on November 6 at the edge of the solar disk and was sent to the other side of the Earth.
The sun rotates, from this it seems that the active region moves across the disk.
The Sun took a pot shot with a plasma unprecedented speed. But it's good. ' Charge ' to quickly fly into space without hitting the Earth.
Some media have predicted a strong magnetic storm on Earth, as a result of outbreaks of November 6. Like, they should wait for the November 11-12. Fear of failure in electrical networks, and exacerbation of chronic diseases.
- Such troubles do happen - just a few days after the coronal mass ejections, when the solar plasma reaches the Earth, - told ' KP ' in the Physics Institute of Russian Academy of Sciences ( FIAN). - But not now. November 6 release of the world is not threatened.
- The Sun rotates, - said the expert, Joe Rao, NOAA (Joe Rao), - from this active region rotated to the Earth. And if in the coming days it will flash, comparable in strength to that which was November 6, we feel it. And we shall see. In the form of intense auroral.
However, according to the LPI, we can hardly wait for the lights of the new troubles. It informs:.
' On the Sun finished one of the biggest in this year's burst of flare activity observed from 2 to 8 November 2010. 7 days in the sun, there were 13 outbreaks of class X and above. The maximum surge occurred on 5-6 November, when it was registered the third power of an outbreak of this year - Class M5. 4 '.
The state of the solar atmosphere over the past day ( November 9-10 ) quiet.
With respect to our planet, according to forecasts LPI, in the magnetosphere is expected to calm down until November 18. 19 - a slight enhancement of geomagnetic activity. Magnetic storms - will not be. And there was from 5 to 10 October. Solar wind speed near the Earth 274 kilometers per second.
The solar atmosphere is November 10 look like excited, but the Earth, according to the LPI, not threatened.
MEANWHILE.
And what we have in space weather?.
In the latest press release from FIAN said: ' Russian Federal Space Agency in conjunction with the Physical Institute of Russian Academy of Sciences (FIAN ) and November 8, 2010 started to publish on its web site operational data on space weather.
Under the space weather today meant an ever-expanding class of phenomena, which are recorded in the environment and the near-Earth space, but have an external origin of cosmic. They are: Earth's magnetic field disturbances, abrupt changes in the density of Earth's upper atmosphere after solar flares, long-distance radio communication failure, changes in radiation conditions in near space, as well as the orbits of the spacecraft and interplanetary probes routes.
Most of these factors adversely affect both human health and performance techniques. Of particular importance registration and alert on changes of space weather will become after the conquest of the moon and Mars, are much less protected from external factors than the Earth.
The time update - 30 minutes. '.
