This research is compare of magnetohydrodynamics (MHD) simulation and observational product to solar coronal helmet streamer (SCHS). Magnetohydrodynamics simulation is performed to construct evolution of a solar coronal helmet streamer attaining magnetohydrodynamics stability in solar corona. The dynamical evolution is satisfied by implementing numerical approach to reach complete self-consistent solution through modified general equation of Lagrangian-Navier-Stokes time-dependent. The density profile resulting from numerical solution is compared to the real data derived from large-angle solar coronagraph data taking by a coronagraph satellite. The research product show range of error is 10% with using measure of differential emission. We conclude that the plasma electron density distribution derived from simulation is in accordance with observational data. © Published under licence by IOP Publishing Ltd.
