Notes.

^(a)

The longitude and latitude values are given in the heliographic Carrington coordinate (HGC) system. The locations of the footpoints from the ENLIL simulation are given at 21.5 R_⊙, which is the inner boundary of the simulation, and for the nominal Parker spiral are given at the solar surface.

^(b)

The longitudinal separation angle is calculated from the flare location at 249° longitude (in HGC).

^(c)

Solar wind values from ENLIL simulation used on 2020 November 29 at 13:00 UT.
