Can Ripples on the Sun help Predict Solar Flares?

An X-class solar flare (X9.3) emitted on September 6, 2017, and captured by NASA’s Solar Dynamics Observatory in extreme ultraviolet light.

“If sunquakes can be generated spontaneously in the sun, this might lead us to a forecasting tool, if the transient can come from magnetic flux that has yet to break the sun’s surface, we could then anticipate the inevitable subsequent emergence of that magnetic flux. We may even forecast some details about how large an active region is about to appear and what type — even, possibly, what kinds of flares — it might produce. This is a long shot, but well worth looking into.”

Any breakthrough technology that might provide early warning of a CME (Coronal Mass Ejection) would be a welcome addition for the NOAA Space Weather Prediction Center.

In 2012 a solar storm that would have taken our power grid down barely missed Earth.

“Just because it’s a below-average solar cycle, doesn’t mean there is no risk of extreme space weather,” said Doug Biesecker, panel co-chair and solar physicist at NOAA’s Space Weather Prediction Center, in a statement. “The Sun’s impact on our daily lives is real and is there. (We are) staffed 24/7, 365 days a year because the Sun is always capable of giving us something to forecast.”

In The Black Sky Event we go into the control room at the NOAA Space Weather center and interview one of the foremost experts in the field, Bill Murtaugh.
