A Big Sunspot is Turning Toward Earth
Source - Space Weather News for July 7, 2017: http://spaceweather.com
SUNSPOT TURNS TOWARD EARTH: A new and large sunspot is rapidly growing
on the solar disk, temporarily arresting the sun's plunge into Solar
Minimum. Stretching more than 70,000 km from end to end, the active
region numbered AR2665 has more than doubled in size in 24 hours. This
makes it an easy target for backyard solar telescopes. So far the
growing sunspot has not produced any strong flares, but this could
change if its rapid growth continues apace and destabilizes the
sunspot's magnetic field.
