We construct a stable solution of the problem of vortex reconnection w
ith the boundary in a superconductor under the planar approximation. T
hat is a solution of partial derivative h/partial derivative T = Delta
h + e(-h) H-0 - 1/h such that h(0, t) --> 0 as t --> T. We give a pre
cise description of the vortex near the reconnection point and time. W
e generalize the result to other quenching problems.
