SOLAR WIND CURRENT
1 Surface of the Sun
As the solar wind rises it simplifies until it consists of two polarities separated by the line of the heliospheric current sheet.
2 Corona
In the corona, the solar wind begins to draw out the heliospheric current sheet into space, extending the Sun’s atmosphere out into the rest of the Solar System.
3 Rotation
As the Sun rotates, it causes the heliospheric current sheet to become twisted.
4 Jupiter
Material in the heliospheric current sheet takes three weeks to reach Jupiter. The sheet extends into the Kuiper belt, where Voyager is exploring.
