An image of the solar flare taken using the X-Ray Telescope onboard Hinode on 7 June 2007. This picture shows the flare loops in the solar atmopshere at temperatures exceeding 10 million degree Celsius. The peak temperature of this flare measured by RHESSI, which is sensitive to much higher temeperatures, measured 15 million degrees.
