More Space Weather on the Way

Space Weather News for May 14, 2013

http://spaceweather.com

 

Solar activity is high. During a 24 hour period straddling May 13th and 14th, the sun unleashed three X-class solar flares. These are the strongest flares of the year so far, and they signal a significant increase in solar activity. The source of the flares, a large sunspot on the sun’s eastern limb, appears poised to erupt again as it turns toward Earth. Check http://spaceweather.com for updates and more information.

 

SOLAR ACTIVITY SURGES: A sunspot on the sun’s eastern limb is crackling with powerful X-class solar flares. AR1748 announced itself during the early hours of May 13th with an X1.7-class eruption (0217 UT), quickly followed by an X2.8-class flare (1609 UT) and an X3.2-class flare (0117 UT on May 14). These are the strongest flares of the year so far, and they signal a significant increase in solar activity. NOAA forecasters estimate a 50% chance of more X-flares during the next 24 hours.

    COMMENT:A class X1.2 solar flare occurred today with peak time 01:48 UT, from NOAA
    AR 1748 which has a beta-gamma-delta magnetic configuration. It was
    associated with radio bursts and an increase of GOES proton flux levels,
    now at 5 protons/cm2-s-sr, the threshold of 10 protons/cm2-s-sr will likely
    be reached soon (at >=10 MeV). The increases in proton flux likely come
    from the CME driven shock. If the strong flares from this AR continue, the
    proton increases will likely be more abrupt when the magnetic connection
    between the flare site and the Earth is better (i.e. when the AR is in the
    western hemisphere). A CME was associated with the event, a shock and
    glancing blow can probably be expected at the Earth late on May 16 (CME
    speed 1700 km/s in LASCO C2). Geomagnetic conditions are quiet, but ACE
    data shows a disturbance starting this morning, with currently magnetic
    intensity close to 15 nT (northwards, so no geomagnetic effect). There is
    not enough data yet to discern clearly its cause, but it is likely related
    to the CME on May 12 (and possibly those from the two previous days related
    to X-flares from NOAA AR 1748). Geomagnetic conditions are expected to be
    unsettled to active, with possible isolated minor storm periods.
    TODAY’S ESTIMATED ISN : 099, BASED ON 11 STATIONS.
