According to Space Weather, Sunspot 1476 poses a threat for X-class solar flares.
SOLAR ACTIVITY INTENSIFIES: Huge sunspot AR1476 is crackling with M-class solar flares and appears to be on the verge of producing something even stronger. The sunspot’s ‘beta-gamma-delta’ magnetic field harbors energy for X-class flares, the most powerful kind. Earth is entering the line of fire as the sunspot rotates across the face of the sun.
Earlier today, amateur astronomer Thomas Ashcraft of New Mexico detected strong shortwave radio bursts coming from the sunspot. “The strongest burst so far occured around 1631 UT on May 9th,” reports Ashcraft. “I am observing at 28 MHz and 21.1 MHz. As I send this note I am hearing more bursting, indicating powerful magnetic dynamism within active region 1476.”
Solar radio bursts are caused by plasma instabilities that ripple through the sun’s atmosphere in the…
