Today at 00:29 UTC we saw a surprise M6.7 solar flare from sunspot region 2529. It was an eruptive event and a coronal mass ejection was launched into space. Be sure to read the news article that we released earlier today for more information.
After almost silently transiting the Earth-facing solar disk it didn't look like sunspot region 2529 had the capacity to let loose a strong solar flare. Today at 00:29 UTC it showed that it was a deceiving silence as it found the energy to produce the strongest solar flare of 2016 thus far: M6.72.
