Its brightness has allowed us to acquire a high signal‐to‐noise ratio (∼80), high‐resolution (∼6 km s−1) spectrum using the HIRES echelle spectrograph on the 10 m Keck I telescope. Given the quality of the data, these observations provide an unprecedented view of associated and intervening absorption systems. Here we announce the availability of this spectrum to the general astronomical community and present a brief analysis of some of its main features.
