Transient feature, SO_2005XN, seen by SO during CR2231. There is a smooth rotation in the magnetic field, indicating a flux rope with radial minimum variance direction. PAS measurements indicate that the sign of σ_C reverses across the boundary marked as a HCS crossing. A similar flux rope structure was observed on the next solar rotation by PSP (Fig. 4) at the same distance and longitude. Like the PSP observations, there is a reversal in the field, although this occurs ∼3 days after the flux rope in this case.
