Query: Is Voyager 1 Inside an Interstellar Flux Transfer Event?   Plasma wave observations from Voyager 1 have recently shown large increases
in plasma density, to about 0.1 cm^{-3}, consistent with the density of the
local interstellar medium. However, corresponding magnetic field observations
continue to show the spiral magnetic field direction observed throughout the
inner heliosheath. These apparently contradictory observations may be
reconciled if Voyager 1 is inside an interstellar flux transfer event - similar
to flux transfer events routinely seen at the Earth's magnetopause. If this
were the case, Voyager 1 remains inside the heliopause and based on the Voyager
1 observations we can determine the polarity of the interstellar magnetic field
for the first time.
