Fig. 4From: Development of a coronal mass ejection arrival time forecasting system using interplanetary scintillation observations(Left) Density distribution on the ecliptic plane estimated by RUN2 at 1:00 UT. (Right) Density distribution on the Sun–Earth plane inclined 90° from the ecliptic plane. Location of the Earth is at [216, 0] as indicated by the large white circle. A smaller white circle estimates the location of Mercury projected onto these planes. Horizontal and vertical axes: distance from the Sun (Rs). Color: electron density (/cc)Back to article page
