摘要：
The curvature of thin coronal rays was measured during their passage above the solar polar regions. We found that the coronal rays were convex in the direction of their motion along the position angle. The pattern illustrates clearly Parker's idea on the spiral interplanetary magnetic field formation. However, the amount of deviation from radial direction was found to be 2-3 times larger than that estimated using the simple relation obtained from the conservation of angular momentum of a gas jet emitted by a rotating body. We discuss a possible reason for the discrepancy.
