  PHOBOS is one of four experiments studying the Au-Au interactions at RHIC.
The data collected during the first few weeks after the RHIC start-up, using
the initial configuration of the PHOBOS detector, were sufficient to obtain the
first physics results for the most central collisions of Au nuclei at the
center of mass energy of 56 and 130 AGeV. The pseudorapidity density of charged
particles near midrapidity is shown and compared with data at lower energies
and from $pp$ and $p\bar{p}$ collisions. The progress of the analysis of the
data is also presented.PHOBOS is one of four experiments studying the Au-Au
