Our Sun Fires off an X-Class Flare!
One of the largest sunspots of the current solar cycle (SS#24) emerged over the sun's eastern limb three days ago and now has unleashed a giant X3-class flare!
NASA's Solar Dynamics Observatory recorded the extreme ultraviolet flash at about 5:15 pm local time. Although the flare was very intense, it was brief and this should help to mitigate any impacts on Earth.
However, the blast is associated with sunspot AR1890 which has become increasingly active over the last 24 hours.
This image courtesy SpaceWeather.gov shows the progression in solar activity since early this morning.
The sunspot in question, located in the lower-left hemisphere of the sun, is slowly rotating towards us and poses a high risk of additional eruptions over the next few days.
Earlier today, AR1890 unleashed an M2.5 class flare. See video of that eruption below.
