Interesting, there has been relatively little solar activity of late which may have some impact on such events.
This image may show the source of the flare, a nice picture.

I have not found the report yet but quite recently a solar flare also pushed out a significant gamma ray pulse. If I find it, will add the link. Edit: Here is the image captured by the FERMI satellite. http://apod.nasa.gov/apod/image/1203/GraySun2panelLabel.jpg

Have noted that there have been a few new studies of late regarding the Suns interactions with the Earth. This one from a few months back identifies an energy path via the Solar wind and magnetic field interactions.

Scientists discover surprise in Earth's upper atmosphere

By Stuart Wolpert September 09, 2009

UCLA atmospheric scientists have discovered a previously unknown basic mode of energy transfer from the solar wind to the Earth's magnetosphere. The research, federally funded by the National Science Foundation, could improve the safety and reliability of spacecraft that operate in the upper atmosphere.

"It's like something else is heating the atmosphere besides the sun. This discovery is like finding it got hotter when the sun went down," said Larry Lyons, UCLA professor of atmospheric and oceanic sciences and a co-author of the research, which is in press in two companion papers in the Journal of Geophysical Research.

The sun, in addition to emitting radiation, emits a stream of ionized particles called the solar wind that affects the Earth and other planets in the solar system. The solar wind, which carries the particles from the sun's magnetic field, known as the interplanetary magnetic field, takes about three or four days to reach the Earth. When the charged electrical particles approach the Earth, they carve out a highly magnetized region — the magnetosphere — which surrounds and protects the Earth.

Charged particles carry currents, which cause significant modifications in the Earth's magnetosphere. This region is where communications spacecraft operate and where the energy releases in space known as substorms wreak havoc on satellites, power grids and communications systems.

The rate at which the solar wind transfers energy to the magnetosphere can vary widely, but what determines the rate of energy transfer is unclear.

¡Hi, CFT!

imagine." (Haldane)

Thanks God, we are yet far from being bored.

My best regards,
