Submission + - A Quiet Sun (journalofcosmology.com)
guigue writes: Although NASA revealed this week a spectacular movie of a Solar Coronal Mass Ejection (CME) that produced intense geomagnetic activity on Earth, including aurorae, some scientists believe that the Sun entered a long Quiet phase that will last at least 100 years. Similar long calm periods are known in the past history of the Sun, and are called "Grand Minima". It is expected that during the maximum of the current solar cycle, late in 2013, the Sunspot Number will be no greater than 55, a value less than one third smaller than the one registered during the previous solar maximum in 2001, and the smallest during the last century.
