Right now, today, one of the largest sunspot groups of Cycle 24 – AR1890 – is pointing nearly strait at Earth.
AR1890 has already produced a large X-class Level 3 solar flare Monday. from Spaceweather.com:
X3-CLASS SOLAR FLARE: Earth-orbiting satellites have just detected an X3-class solar flare from big sunspot AR1890 (Nov. 5th @ 2211 UT).
Here is the X-ray event recorded by the satellites:
And here is video of the AR1890 group burping out an M-Class 3.8 flare yesterday:
UPDATE: Close up movie of AR1890
Long-term, everyone knows we are inching into an extended quiet period of solar inactivity.
Today, and the next couple days, are a very notable exception.
