A Long, Bright Flare

The X-ray Telescope tracked AR12371 for most of the week. This active region is responsible for several flares and even some beautiful Aurora Borealis. On 25 June 2015, XRT observed this long duration M7.9 flare. The movie above shows XRT's view of the flare in the thin_Be filter along with a GOES X-ray flux plot showing the X-ray irradiance of the sun. The vertical red line in the plot corresponds to the time of the X-ray image above.

As you watch the movie, you'll notice that there are a few gaps where XRT did not observe the flare. These times correspond to when XRT was eclipsed by the earth. Hinode orbits the earth in a polar orbit, which allows an almost continuous view of the sun. However, during the summer months, the earth will sometimes be between XRT and the sun, obstructing the view. Nonetheless, we still gain an interesting depiction of how this event unfolded.
