For those who keep up with the sun check this out. Magnificent Active Region. Sunspot 1087 has a magnetic canopy that can only be described as
magnificent. It's on full display in today's extreme ultraviolet image from the Solar Dynamics Observatory:
Note the inset. The active region could swallow our planet ten times over and still have room to spare. Fortunately, we're 93 million miles away. We
could still feel the effects of an eruption, however. The thicket of magnetic loops and filaments harbors energy for M-class solar flares. M-flares
can heat and puff up Earth's upper atmosphere, causing satellites to experience extra drag as they orbit our planet; they can also cause waves of
ionization to ripple around the planet, disrupting radio communications. There haven't been any big eruptions yet, but the magnificent magnetic field
of sunspot 1087 has been restless, as shown in this time-lapse movie spanning four days.
NOAA forecasters estimate a 10% chance of M-flares during the next 24 hours. Readers with solar telescopes are encouraged to monitor developments.
