JoeRobe writes "According to spaceweather.com, a major X5 solar flare is on its way to deliver a glancing blow to the Earth's magnetic field. This is the second x-class flare to be released by the same sunspot in the past few days, the first being an X1. In both cases, the sunspot (spot 1429) was not directly facing Earth, but it is still active, and poses a threat for a large, Earth-directed flare in the next few days."
