AB: Conjugate studies of high-latitude geomagnetic activity provide understanding of the global magnetospheric reaction to external perturbations and the role of the ionosphere in modulating and coupling with the magnetosphere. Interhemispheric asymmetries as manifested in auroral emissions have been observed for over 40 years. Until recently, the nature of the problem limited the type and extent of studies that can be performed to either conjugate ground based observations or comparison of space based images from all-sky cameras. With the availability of multiple space-based observing platforms, observations of conjugate aurora have been performed, primarily on an event basis. In this paper, initial results are presented of a statistical comparison of conjugate auroras as seen by Polar/UVI and IMAGE/FUV between 2001 and 2003. A database of over 900 potential conjugate observing periods is used to select auroral images for study. Comparisons include statistical intensity distributions, auroral power and relative substorm onset timing and substorm evolution.
