HUGE SUNSPOT: One of the biggest sunspot groups in many years has just emerged over the sun's eastern limb. The sunspot's magnetic canopy is crackling with M-class (medium-sized) solar flares and seems poised to launch even stronger X-class eruptions. The sunspot, named AR1339, is not yet directly facing Earth but it will be turning toward our planet in the days ahead. Check http://spaceweather.com for images of the behemoth and updates.
SUNSPOT TELESCOPE: Sunspot AR1339 looks magnificent when viewed through Explore Scientific's White Light Solar Observing System. This safely-filtered telescope is designed for high-quality imaging of sunspots and it is now available in the Space Weather Store: http://www.shopspaceweather.
