..um lindo vôo sobre uma bela camada de STRATUS,
e o sol nem apareceu..

choveu chato depois, vortei para a serra..escuro aqui tambem, muita coisa pra fazer em casa..

boa noite, friends, grato pela visita, até amanhã..

verifique os anteriores, e êsse vídeo incrível
de um belo "flare" solar..

BAAAAH, ÊSSE VÍDEO COM ESSA MUSICA, VEJA COM TELA CHEIAA!







A solar flare is a violent explosion in a star"s (like the Sun"s) atmosphere releasing up to a total energy of 6 × 1025 Joules.[1] Solar flares take place in the solar corona and chromosphere, heating plasma to tens of millions of kelvins and accelerating electrons, protons and heavier ions to near the speed of light. They produce electromagnetic radiation across the electromagnetic spectrum at all wavelengths from long-wave radio to the shortest wavelength gamma rays.[2] Most flares occur in active regions around sunspots, where intense magnetic fields emerge from the Sun"s surface into the corona. Flares are powered by the sudden (timescales of minutes to tens of minutes) release of magnetic energy stored in the corona.

X-rays and UV radiation emitted by solar flares can affect Earth"s ionosphere and disrupt long-range radio communications. Direct radio emission at decimetric wavelengths may disturb operation of radars and other devices operating at these frequencies.

Solar flares were first observed on the Sun in by Carrington and independently by Hodgson in 1859 as localized brightenings in a sunspot group. Stellar flares have also been observed on a variety of other stars.

The frequency of occurrence of solar flares varies, from several per day when the Sun is particularly "active" to less than one each week when the Sun is "quiet". Large flares are less frequent than smaller ones. Solar activity varies with an 11-year cycle (the solar cycle). At the peak of the cycle there are typically more sunspots on the Sun, and hence more solar flares.
