SOHO Coordinate Information

Updated plot showing the path of Mercury with respect to EIT field-of-view

SOHO coordinates below in the GSE RLP frame. Time is UTC. The states are in X,Y,Z, Vx, Vy, Vz order in units of km and km/sec. At these epochs SOHO is just a few days or so beyond an RLP XZ plane crossing and well south--about 133,000 km--of the ecliptic plane.
