Abstract
This note is concerned with gauge choices for the time-dependent GINZB URG-LANDAU equations of superconductivity. The equations model the sta te of a superconducting sample in a magnetic field near the critical t emperature. Any two solutions related through a ''gauge transformation '' describe the same state and are physically indistinguishable. This ''gauge invariance'' can be exploited for analytical and numerical pur poses. A new gauge is proposed, which reduces the equations to a parti cularly attractive form.
