| "There is a theory which states that if ever anybody discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable. There is another theory which states that this has already happened." *** |

Flare 04-09-2008: Left: Original (Exposure-filtered and Byte-Scaled).
Right: Sharpened (Exposure-filtered, ~ Flattened, ~ Run-Mean-Differenced, Byte-Scaled).
The movie will loop backward to make movements even clearer. Watch for flows
moving in and out from the Sun (count at least 3) and some seeming to originate from a
common region just before the large time gap!

Stack-Plot: Stack plot from the sharpened data set. The slit was rotated in stages to match the flow path direction. The first and last slits are shown overlaid onto the original data set (inset). The slit stages are separated by white columns. Black columns indicate time gaps. The dashed column indicates a large data gap occurring between 13:25 and 16:25 UT. A disconnection event is observed between 13:04 and 13:25 UT. Note the bright "boomerang" feature visible in the stack plot in this time range.
Manual Tracking: This image set was produced by manually tracking the flows (both in and out from the solar surface). The two left panels are of the original data with different scaling. The middle right panel is the sharpened data from above. The right-most panel is the sharpened data after applying hist_equal and smooth.

Track overlays of the manually-tracked flows (plane-of-sky).
3D + PFSS Track Overlays: This image set was produced by overlaying the tracks determined above onto the images provided using sswidl's PFSS_viewer routine and then using the approximate longitude and latitude to de-project the tracks.
