Incrível a projeção da explosão e a Terra. Vivas a distância!!!
The Sun released two significant solar flares on Sept. 6, including one that clocked in as the most powerful flare of the current solar cycle.
The solar cycle is the approximately 11-year-cycle during which the Sun’s activity waxes and wanes. The current solar cycle began in December 2008 and is now decreasing in intensity and heading toward solar minimum, expected in 2019-2020. Solar minimum is a phase when solar eruptions are increasingly rare, but history has shown that they can nonetheless be intense.

Our Solar Dynamics Observatory satellite, which watches the Sun constantly, captured images of both X-class flares on Sept. 6.
Solar flares are classified according to their strength. X-class denotes the most intense flares, followed by M-class, while the smallest flares are labeled as A-class (near background levels) with two more levels in between. Similar to the Richter scale for earthquakes, each of the five levels of letters represents a 10-fold increase in energy output.
The first flare peaked at 5:10 a.m. EDT, while the second, larger flare, peaked at 8:02 a.m. EDT.

Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth’s atmosphere to physically affect humans on the ground, however — when intense enough — they can disturb Earth’s atmosphere in the layer where GPS and communications signals travel.
Both Sept. 6 flares erupted from an active region labeled AR 2673. This area also produced a mid-level solar flare on Sept. 4, 2017. This flare peaked at 4:33 p.m. EDT, and was about a tenth the strength of X-class flares like those measured on Sept. 6.

This active region continues to produce significant solar flares. There were two flares on the morning of Sept. 7 as well.

From the article: “Some of Japan’s colors have a lengthy background dating back to the Asuka period (538 ~ 710) and the hierarchical Japanese color system itself can be most easily traced back to 603 AD, when Prince Shōtoko established the first Twelve Level Cap and Rank System in Japan. Based on Confucian values and the five Chinese elements (wood, fire, earth, metal, and water), this particular hierarchy determined one’s rank by quality, rather than one’s heritage. Ranks were made identifiable by specific colors, as follows:
大徳 (Daitoku) Greater Virtue
小徳 (Shōtoku) Lesser Virtue
大仁 (Daijin) Greater Benevolence
小仁 (Shōjin) Lesser Benevolence
大礼 (Dairei) Greater Propriety
小礼 (Shōrei) Lesser Propriety
大信 (Daishin) Greater Sincerity
小信 (Shōshin) Lesser Sincerity
大義 (Daigi) Greater Justice
小義 (Shōgi) Lesser Justice
大智 (Daichi) Greater Knowledge
小智 (Shōchi) Lesser Knowledge
Within this system, the kinkiji (禁色), meaning “forbidden colors” were exclusively designated for use by only the highest ranking government officials and their robes. For example, the robes of the kuge (公家, the dominant aristocratic class in Kyoto’s imperial courts) were of the color Ōtan (orange), therefore the use of this color by any other lower rank was strictly prohibited.
As such, the warm orange and red hues came to be associated with power and affluence. Examples of this can also be found in everything from ornamental combs and katana scabbards to the torii gates of Shinto shrines and the shrine-maidens’ garb. On the opposite end of the spectrum (ha!), the yurushiiro (許し色, “permissible colors”) were usable by commoners.”
I find it particularly interesting that at this early period in Japanese development, they were of course still using Chinese philosophy and science to systematically organize something very abstract and unscientific as what color clothes you should wear– and not only that, but using Chinese science to determine that some colors should be forbidden in society to some people, and thus literally color-code peoples’ castes using a color system based on magic! :)

<p>Para os meus netos. Quando do término da minha graduação elaborei algumas peças em feltro para auxiliar a alfabetização de crianças. <br> Bem, pensei que usariam com meus futuros alunos. Só pensei, pois não os tive. Quanto aos projetos os acumulei e não parei de cultivar a minha mente e furar os meus dedos.<br> Voltei a eles, com pontos e linhas coloridas. <br> São para os meus netos.
