SDO has taken an image of "golden" in the middle: it is an extreme ultraviolet image of the sun. A flash of UV radiation is centered on the sunspot 1158 and is listed as the largest solar flare since December 2006. SOHO took the photo red on the outside, and an image is the coronagraph. The flow that hit the Earth today is visible as a cloud soaring flying away from the solar disk.
The Valentine's Day, the joy of flowers and chocolates vendors, our star has literally shot the last of three flares, occurred on 13, 14 and 15 February respectively, and all caused by enlargement of a normal sunspot.
These regions are irregularly shaped and rather limited in the Sun's surface are called "spots" since the days of Galileo Galilei simply because they are darker because the rest of the colder surface.
generate sudden release of energy caused by the solar magnetic field. At this sudden and massive release of energy is followed by an actual series of explosions in the Sun's surface material or gas 5-6000 degrees.
is ejected outward up at distances of millions of miles at high speed, along with swarms of elementary particles, anche queste in quantità straordinaria.
Nelle ultime settimane si era risvegliata una certa attività sulla superficie solare presentando brillamenti anche maggiori di questo, ma si erano verificati nella parte del Sole opposta alla posizione Terra. Questa volta invece è accaduto il contrario. La classe X infatti è rara (ne scrivemmo già in passato su Antares Notizie)ed è una misura di intensità dei brillamenti più potenti e l'ultimo di questa intensità si era registrato nel 2006.
Le radiazioni e le particelle che stanno arrivando "sparate" verso di noi verranno in parte deviate dallo scudo naturale del nostro campo magnetico terrestre e le altre non dovrebbero creare grossi problemi, se non qualche interference with telecommunications, satellites and between species in the field of short waves, practically not used by us common citizens.
effects on the distribution networks of electricity were recorded in 2003 and only in very limited regions of North America.
NEWS: The CME reached the Earth's magnetic field at about 01:00 UT today February 18 (8:00 pm EST February 17). The impact was not as strong as expected considering the source of class X of the cloud. However, are possible in the coming hours and geomagnetic storms were alerted observers to the high latitudes because they can easily verify spectacular auroras.
