  We present analysis and photoionization modeling of the Chandra high
resolution spectrum of Mrk 279. There is clear evidence of an absorbing outflow
which is best fit by a two component model, one with a low ionization parameter
and one with a higher ionization parameter. The column density of the X-ray
warm absorber, about log N_H=20, is the smallest known of all AGNs in which
X-ray absorbing outflows are observed. We find that the X-ray and UV/FUV
absorbers are part of the same overall outflow. There is some evidence of
super-solar carbon, nitrogen, oxygen and iron in the Chandra spectrum of Mrk
279. While this is not a robust result in itself, Chandra data in combination
with the UV data and the pressure equilibrium between two phases of the
outflow, support the scenario of super-solar abundances. This the first case
where super-solar abundances are reported in the nucleus of a normal Seyfert
galaxy. The data suggest that the outflow originates from a compact region
around the nuclear black hole and that it carries insignificant amount of mass
and energy.
