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.

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.
