1207.3952 (Gareth Dorrian et al.)

Equatorwards Expansion of Unperturbed, High-Latitude Fast Solar Wind    [PDF]

Gareth Dorrian, Andy Breen, Richard Fallows, Mario Bisi
We use dual-site radio observations of interplanetary scintillation (IPS) with extremely long baselines (ELB) to examine meridional flow characteristics of the ambient fast solar wind at plane-of-sky heliocentric distances of 24-85 solar radii (R\odot). Our results demonstrate an equatorwards deviation of 3-4{\deg} in the bulk fast solar wind flow direction over both northern and southern solar hemispheres during different times in the declining phase of Solar Cycle 23.
