Today one year ago: X9.3 solar flare
It has been many months since we've last seen a strong solar flare or even a decent sunspot region. It is no secret that we are well on our way to solar minimum. However, today exactly one year ago, our Sun looked very different compared to how it looks today. Multiple sunspot regions were visible but by far the most interesting sunspot region was sunspot region 2673. Sunspot region 2673 was on 6 September 2017 one of the most complex sunspot regions that we have seen this solar cycle and it erupted that day with an X9.3 (R3-strong) solar flare which will likely remain the strongest solar flare of the current solar cycle, solar cycle 24.
