Newly reported observations of gas flows on the solar surface may explain why the sun recently had such an extended case of the doldrums.
From 2008 through the first half of 2009, the sun had a puzzling dearth of sunspots, flares and other storms, extending the usual lull at the end of the 11-year solar activity cycle for an extra 15 months.
