Sunspot region 2673 YouTube video
Thursday, 14 September 2017 22:11 UTC
Solar activity has plunged to very low levels with the disappearance of sunspot region 2673.
What a week it was. Sunspot region 2673 grew from a simple Alpha sunspot to one of the most complex sunspot regions of Solar Cycle 24 in just 48 hours. It managed to produce a mind blowing 27 M-class solar flares and 4 X-class solar flares, including the strongest and second strongest solar flare of Solar Cycle 24. To top it of, it even caused a severe G4 geomagnetic storm at Earth.
A sunspot region to remember for sure. We look back at this hectic week in our latest YouTube video where we look at the development of sunspot region 2673, the X-class solar flares and the M5.5 solar flare that launched a coronal mass ejection towards our planet. The video is full with never before seen footage so be sure to check it out!
