New results are presented for a mosaic mapping of the H I in the field of t
he Local Group dwarf galaxy Phoenix. The observations, obtained with the Au
stralia Telescope Compact Array, cover an area of similar to 2 degrees x 2
degrees. Four velocity components are identified, at heliocentric velocitie
s of -23, 7, 59, and 140 km s(-1). While the gas at 7 km s(-1) is of Galact
ic origin and the gas at 140 km s(-1) is most likely associated with the Ma
gellanic Stream, the situation for the two other components is unsure. Howe
ver, it is suggested that the component at -23 km s(-1) is probably associa
ted with Phoenix because: (1) it has a compact structure and is only slight
ly offset from the optical image, (2) its H I mass of similar to 10(5) M. i
s what can be expected in such a system, 3) it has a definite velocity grad
ient, (4) its location west of Phoenix is compatible with the already suspe
cted self-propagation from east to west of the last star formation episode.
Because of the large mass (similar to 5 x 10(6) M.) implied if at the dist
ance of Phoenix and also because of its large extent, the component at +59
km s(-1) is most likely not associated. Optical velocities are still needed
to confirm or not those possible associations.
