SMEI Activities

Video presentations are available for a combination of the Helios spacecraft-derived perspective views of inner heliospheric plasma density and a CME analyzed by Jackson and Hick (Third SOHO Workshop Conference, ESA SP-373, 233, 1994). The presentations are cartoons of how heliospheric plasma density might look as a CME progresses through the interplanetary medium to Earth at the rate of 400 km/s. The views are 90 degrees wide and centered on the Sun. The image and a 3.6 Mbyte *.avi or a 2.1 Mbyte quicktime video shows the perspective view from Earth for a single rotation of the Sun. The CME arrives at Earth about midway through the video. The image and a 4.7 Mbyte *.avi or a 3.5 Mbyte quicktime video shows the perspective view from an ecliptic location 1.7 AU from the Sun 30 degrees above the ecliptic plane and 45 degrees east of the sun from the Earth at the beginning of the video sequence.
