"When the week began, the sun hadn't unleashed an X-flare all year long. In only two days, sunspot AR1748 has produced four. In summary, AR1748 has produced an X1.7-class flare (0217 UT on May 13), an X2.8-class flare (1609 UT on May 13), an X3.2-class flare (0117 UT on May 14), and an X1-class flare (0152 on May 15). These are the strongest flares of the year, and they signal a significant increase in solar activity."
X-class solar flares are the highest intensity -- capable of altering magnetics on Earth in significant ways, and having major effects on our physical, mental and emotional magnetic fields.
These flares were not directed toward Earth, so we won't be feeling their direct effects, perhaps more like a "glancing blow" -- but evidently this sunspot is still very active, so it bears continued watching. Stay tuned!
