We have obtained low resolution (20 Å FWHM) slit spectra of 10 quasar candidates located within one degree of the quasar Q0122-380 with the objective of searching for signs of large scale structure matching the intervening rich absorption complexes seen over the redshift range toward this object. Of the 8 confirmed quasars, 4 turn out to have redshifts , placing them well in front of the redshift range of interest. Two of the three confirmed quasars at redshift show no obvious absorption matching that of Q0122-380 at our spectral resolution and signal-to-noise ratio. The third object at a redshift of displays strong absorption systems at and and a possibly BAL-like trough at . If not intrinsic in nature, the former two systems could potentially be related to the absorption seen in Q0122-380, albeit over a distance of ( Mpc at ).
