    On June 11, 2014, the sun erupted with its third X-class flare in two days. The flare was classified as an X1.0 and it peaked at 5:06 a.m. EDT. Images of the flare were captured by NASA's Solar Dynamics Observatory. All three flares originated from an active region on the sun that recently rotated into view over the left limb of the sun.

    To see how this event may affect Earth, please visit NOAA's Space Weather Prediction Center at http://spaceweather.gov, the U.S. government's official source for space weather forecasts, alerts, watches and warnings.

    For anyone wondering what's the Ratings/differences in Flares.

    There are 9 sunspots visible, with a new region coming into view. I'd say we would need a strong flare to see anything this far south. Maybe a kp index of 7 or 8. That would want to be a direct hit cme.
    A somewhat busy day on the space weather front, so I will provide you with this secondary solar update.

    Here is an updated look at the visible solar disk. New regions 2160, 2161 and 2162 were all assigned today. Each are not considered a threat for strong solar flares at this time. Another new region is now just beginning to turn into view off the east limb. We will get a better look within the next 24 hours.

    The C8.0 solar flare Saturday morning around region 2157 appears to have been responsible for a coronal mass ejection (CME) as seen in the attached image by LASCO C2. It does not appear to be Earth directed.

    The Solar X-Rays are active once again. Region 2157 produced a moderate M1.1 solar flare at 17:09 UTC. The active region continues to evolve and will remain a threat for additional moderate to strong solar flares.

    ACE spacecraft data showed an increase in solar wind speed on Saturday morning and it could be related to an expected glancing blow CME impact. A geomagnetic sudden impulse was also detected at 15:25 UTC. Increased geomagnetic activity will be possible in the hours ahead. More updates to follow if required.



    Geomagnetic Storm Watch
    A minor geomagnetic storm watch is in effect for the next 24-48 hours. A large filament eruption observed on Tuesday generated a CME that may deliver a glancing blow to our geomagnetic field. Sky watchers at high latitudes should remain alert as we head into the weekend.

    New Data Center Protects Against Solar Storm and Nuclear EMPs
    "In Boyers, Pa., a recently opened 2,000-sq.-ft. data center has been purpose-built to protect against an electromagnetic pulse (EMP), either generated by a solar storm or a nuclear event. The company that built the facility isn't disclosing exactly how the data center was constructed or what materials were used.

    But broadly, it did say that the structure has an inner skin and an outer skin that use a combination of thicknesses and metals to provide EMP protection. Betting against an EMP event is a gamble. In 1859, the so-called Carrington solar storm lit the night skies and disrupted the only telegraph communications. William Murtagh, program coordinator at U.S. Space Weather Prediction Center, said there is ongoing concern that the earth may see an solar storm that could impact electronics on the ground. "We're concerned that can happen,"

    A 2012 solar storm, that missed the earth, "was very powerful, and some have suggested it would have been on par with a Carrington-level event." One researcher put the odds of a catastrophic solar storm by 2020 as one in eight.

    NASA spacecraft provides new information about sun's atmosphere
    NASA's Interface Region Imaging Spectrograph (IRIS) has provided scientists with five new findings into how the sun's atmosphere, or corona, is heated far hotter than its surface, what causes the sun's constant outflow of particles called the solar wind, and what mechanisms accelerate particles that power solar flares.
