The stability of the equilibrium orientation of l parallel or antiparallel to a counterflow is studied both dynamically and statically. In contrast to the recent work of Hall and Hook (1977) - who, it is shown, use incorrect dynamical equations - the equilibrium is found to be stable in the Ginzburg-Landau regime. At lower temperatures an instability should develop.

Additional Information:© IOP Publishing Limited 1978. Received 1 November 1977. Print publication: Issue 9 (14 May 1978) This work was stimulated by correspondence or conversations with HE Hall, AL Fetter, ND Mermin, T-L Ho and WF Brinkman. Note. On completion of this work we received a preprint from P Bhattacharya, T-L Ho and ND Mermin who also prove the stability of the equilibrium in the Ginzburg-Landau regime. The emphasis of their paper is on the behaviour with an instability. Our results complement theirs on the existence of an instability. We have since heard that the preprint Hook and Hall (1977) has been withdrawn, following the criticisms detailed above. Apparently the controversy over the correct orbital dynamic equations has now been settled.
