Massive X-Class Solar Flare

    NASA image captured 9 Aug 2011.

    On August 9, 2011 at 3:48 a.m. EDT, the sun emitted an Earth-directed X6.9 flare, as measured by the NOAA GOES satellite. These gigantic bursts of radiation cannot pass through Earth's atmosphere to harm humans on the ground, however they can disrupt the atmosphere and disrupt GPS and communications signals. In this case, it appears the flare is strong enough to potentially cause some radio communication blackouts. It also produced increased solar energetic proton radiation -- enough to affect humans in space if they do not protect themselves.

    There was also a coronal mass ejection (CME) associated with this flare. CMEs are another solar phenomenon that can send solar particles into space and affect electronic systems in satellites and on Earth. However, this CME is not traveling toward and Earth so no Earth-bound effects are expected.

      It truly is amazing the things that go on in outer space. So close to home and the majority of us are totally oblivious! I love it!

      Beautiful picture!

      I lost my connection (major outage in my neighborhood) this morning about the same time, I wonder if this is why!
