Sun erupts with major solar flare
The sun erupted with one of the strongest solar flares it can unleash early Friday, Oct. 25, just days after firing off an intense solar storm at Earth.
The major solar flare, which registered as an X1.7-class solar event on the space weather scale, peaked at 4:01 a.m. EDT (0801 GMT), according to an alert by the NOAA-run Space Weather Prediction Center. NASA’s Solar Dynamics Observatory captured video of the X1.7 solar flare, which followed several smaller sun storms over the last few days.
The sun storm erupted from a new sunspot cluster called Region 1882 and sparked a temporary radio blackout, SWPC officials said in an update. But it is not aimed directly at Earth and is not currently expected to be “geo-effective,” meaning that it should not spark a major geomagnetic storms in Earth’s magnetic field, they added.
Astronomers classify solar flares into three categories — C, M and X — with C being the weakest and X the strongest. When aimed directly at Earth, X-class sun eruptions can interfere with satellite-based communications and navigation systems, endanger astronauts in orbit.
