Abstract:

In may, 1993, the heliopheric current sheet (HCS) ceased to be seen by the Ulysses spacecraft at a heliocentric latitude of ~30degrees S and distance of 4.7 AU. The disapearance of the HCS coincided with the solar wind speed remaining >560km/s and with the disappearance of one of four interaction regions previously seen on each solar rotation.
