With an optical R-band magnitude of 15.2, the recently discovered z=3.911 BALquasar APM 08279+5255 is an exceptionally bright high redshift source. Itsbrightness has allowed us to acquire a high signal-to-noise ratio (~100), highresolution (~6 km/s) spectrum using the HIRES echelle spectrograph on the 10-mKeck I telescope. Given the quality of the data, these observations provide anunprecedented view of associated and intervening absorption systems. Here weannounce the availability of this spectrum to the general astronomicalcommunity and present a brief analysis of some of its main features.Comment: 21 pages including 5 figures.
