According to Spaceweather.com : Since Jan. 3rd, sunspot AR3947 has produced three X-flares and dozens of M-class solar flares. All that activity yielded zero significant CMEs. What happened? Flares and CMEs are two different aspects of exploding sunspots, and they don't always happen at the same time. Dozens of flares with zero CMEs is a little unusual, but not unprecedented. The opposite can happen, too. AR3947 might suddenly start producing CMEs with no significant flares. It would certainly improve the aurora forecast.
