Geometries of the rain bow from the stereoscopic reconstruction (S) and from the magnetic field extrapolation (E13 and E98), viewed from the position of SDO (a), STEREO B (b), and near the solar south pole (c). The heliographic grid is spaced by 10°. The cross indicating the north and east directions on the solar sphere is located at the latitude of −20° and the Carrington longitude of 220°.
