Space Weather Event: The View from Above

We open with a view from high above the ecliptic plane, at the space between the Sun (left) and the Earth (within the small rectangular box on the right). In the plane of the Earth's orbit, we show a 'slice' of the Enlil model showing the particle density profile of the solar wind (white to yellow for decreasing particle density). The spiral 'rotating water sprinkler' pattern in the density is the Parker spiral (Wikipedia).

The CME (orange surface) erupts in the direction of the Earth. The orange surface represents a boundary of common pressure differences, which better identifies sharp transitions in pressure common in shocks fronts. The CME clears out particles in the region behind it, called a rarefaction (Wikipedia), visible in the particle density.

This visualization is part of a series of visualizations on space weather modeling.
