Something a bit alarming to read on awakening:
BIG SUNSPOT ALERT: Yesterday, sunspot AR3038 was big. Today, it’s enormous. The fast-growing sunspot has doubled in size in only 24 hours: movie. AR3038 has an unstable ‘beta-gamma’ magnetic field that habors energy for M-class solar flares, and it is directly facing Earth. [Spaceweather.com]
Granted, M-class is not X-class, but still.
