The presence of dissipation permits slippage of field lines with respect to the plasma, and hence a current sheet can be formed in the presence of smooth photospheric flows. The structure of the current sheet encompasses a thin strip spanning two Y-points. It is shown that the rapid reconnection involved in the formation of the current sheet justifies the use of helicity conservation. Implications for coronal heating and numerical simulations of the corona are discussed.
