AB: Observations of correlated features in the solar wind from two well-separated spacecraft, such as Wind and ACE in 2001-2002, yield information about the variability of the solar source of the wind as well as about evolution of features between the observation points. If their solar sources were independent of time, one would expect features that are not radially expanding as portions of spherical shells to be co-rotating with the Sun as Parker spirals. Previous correlation studies have shown that the average propagation times of features between spacecraft lie between those expected for spherically expanding shells and those expected for co-rotation. Nevertheless, we have found that individual pressure-balanced structures well-correlated in several parameters are consistent with co-rotation provided that the associated magnetic fields are close to the Parker spiral direction. That dependence on field orientation has not been pointed out previously.
