Observations of simultaneous retracting and expanding loops above a flaring arcade
J. I. Khan, L. Fletcher, N. V. Nitta
We present imaging observations from the Yohkoh Soft X-ray Telescope (SXT) which
show the retraction of a coronal loop above a flaring arcade. The shrinking loop
was observed face-on in emission during the decay phase of a solar flare.
At the same time we also observe a faint outward moving loop-like feature above
the flaring arcade and retracting loop. We interpret the shrinking loop and
simultaneous outward moving loop as direct evidence for reconnected magnetic
field lines during a flare.
