BIG SUNSPOT ALERT: Yesterday, sunspot AR2715 did not exist. Today, it sprawls across more than 60,000 km of solar surface with a primary dark core wider than Earth. So far the active region has not produced any big flares, but this could change if its development proceeds apace. Visit today's edition of Spaceweather.com for a video of the sunspot's genesis and information about how it fits into Solar Minimum.
