AB: The open flux is estimated from SuperDARN observations of the convection reversal boundary (CRB). The CRB as a proxy for the OCB was established by Sotirelis et al. [2005]. Since that time the CRB detection algorithm has been improved and a procedure for estimating the open flux from a collection of CRBs devised. The correlation of open flux with solar wind/IMF driving is tested. Since these flux estimates are made every few minutes, the expanding and contracting polar cap conditions may possibly be distinguished. The practicality of using this procedure for this purpose will be tested.
