Solar flare: A big new sunspot is emerging over the sun's northeastern limb - Nuovo brillamento solare nella parte nord-est del Sole

EMERGING SUNSPOT, STRONG FLARE: A big new sunspot is emerging over the sun’s northeastern limb. It announced itself on March 2nd at 1746 UT with an M3-class solar flare. NASA’s Solar Dynamics Observatory recorded the extreme ultraviolet flash.NOAA forecasters estimate a 55% chance of additional M-class flares and a 5% chance of an X-flare during the next 24 hours. Solar activity is picking up. The expanding cloud is not Earth-directed.

Il Solar Dynamics Observatory della NASA ha registrato un nuovo ed importante brillamento solare, un M3-class, con espulsione di massa coronale, da un nuovo spot situato sulla parte nord-est del Sole. La nuvola di radiazioni non sarebbe diretta verso la Terra. Non è escluso che si verifichi altra attività nelle prossime 24 ore.

    Space Weather Message Code: SUM10R
    Serial Number: 530
    Issue Time: 2012 Mar 05 0635 UTC
    SUMMARY: 10cm Radio Burst
    Begin Time: 2012 Mar 05 0334 UTC
    Maximum Time: 2012 Mar 05 0434 UTC
    End Time: 2012 Mar 05 0601 UTC
    Duration: 147 minutes
    Peak Flux: 12000 sfu
    Latest Penticton Noon Flux: 120 sfu
    Description: A 10cm radio burst indicates that the electromagnetic burst associated with a solar flare at the 10cm wavelength was double or greater than the initial 10cm radio background. This can be indicative of significant radio noise in association with a solar flare. This noise is generally short-lived but can cause interference for sensitive receivers including radar, GPS, and satellite communications.
