SOLAR ACTIVITY INTENSIFIES: After months of relative calm, the sun burst back into life yesterday with a remarkable series of M-class solar flares. The fusillade ionized the top of Earth’s atmosphere and caused a rolling global shortwave radio blackout. If current trends continue, an X-flare may be in the offing, with at least one dangerous sunspot directly facing Earth.
