The sun emitted a mid-level solar flare, peaking at 8:13 p.m. EDT on Oct. 1, 2015. NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event. 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 the atmosphere in the layer where GPS and communications signals travel.
NASA's Solar Dynamics Observatory captured this image of a solar flare – as seen in the bright flash on the lower right limb of the sun – at 8:12 p.m. EDT on Oct. 1, 2015. The image is a blend of three wavelengths of extreme ultraviolet light that have been colorized.

To see how this event may affect Earth, please visit NOAA's Space Weather Prediction Center, the U.S. government's official source for space weather forecasts, alerts, watches and warnings.
This flare is classified as an M5.5 class flare. M-class flares are a tenth the size of the most intense flares, the X-class flares. The number provides more information about its strength. An M2 is twice as intense as an M1, an M3 is three times as intense, etc.
Updates will be provided as needed.

el dispensador dice:
hablan los suelos,
hablan los sueños...
hablan los aires,
hablan los vuelos...
hablan los espacios,
sonidos y truenos...
hablan los fuegos,
cenizas crepitando en lo eterno...
hablan las aguas,
fuentes y riegos...
hablan las piedras,
pasos en desfiladeros...
habla el Sol,
pirámides en silencios...
humanos ensimismados,
nada cerca,
todo lejos...
mejor permanece en vigilia,
prudente es estar atento,
cuando el Sol habla distante,
se debe atender a sus ecos vibrantes...
está llegando el momento,
más que momento es instante,
en que los signos son señales,
que se interponen entre el ayer... y el adelante.
