ecliptic latitudes. Science, 268, 1016-1019.
Along Ulysses' path from Jupiter to the south ecliptic pole, the
onboard dust detector measured a dust impact rate which varied slowly
from 0.2 to 0.5 impacts per day. The dominant component of the dust
flux arrived from an ecliptic latitude and longitude of
10\degn$\pm$10\deg and 280\degn$\pm$30\deg which indicates an
interstellar origin. An additional flux of small particles, which do
not come from the interstellar direction and are unlikely to be
zodiacal dust grains, appeared south of -45\deg latitude. One
plausible explanation is that these particles are beta-meteoroids
accelerated away from the Sun by radiation pressure and
electromagnetic forces.
