#Sunspot AR3664, the source of the historic May 10th superstorm, has spent the past two week's transiting the farside of the #sun. Yesterday, it announced its return with an #X2.8-class #solarflare. Amateur #astronomer Michael Karrer was watching the sun when the #explosion occured, and he captured this #picture of flying debris:

"I have not seen an explosion like this in my 40 years of observing the sun," says Karrer. "So fast, so far out into space! It was gigantic."

The explosion caused a deep shortwave radio blackout over east Asia and hurled a bright #CME into #space. A NASA model of the CME confirms that it will miss Mercury, Venus and Earth. None of the inner planets will be affected by this powerful event.
