NOAA forecasters estimate a 75% chance of M-class solar flares and a 20% chance of X-flares during the next 24 hours. Any eruptions are likely to be geoeffective because the source, sunspot AR1476, is directly facing our planet.
Yesterday, May 10th, amateur astronomer David Maidment of Sohar, Oman caught the active region in mid-flare during a strong M5-class eruption:
The blast, which almost crossed the threshold into X-territory, did not produce a significant coronal mass ejection (CME). “There seemed to be no CME due to the fact that the plasma was captured and dragged back down to the sun,” notes Maidment.
