Abstract: We present a large (roughly 10 Mpc) void in the Ly-alpha forest in the spectrum of a zem = 3.285 quasar, Q0302-003. We discuss the possibility that it results from ionization of the clouds by the UV radiation of a bright foreground quasar, Q0301-005 (zem = 3.223). We present a model of the influence of quasars on the Ly-alpha forest and show that in order to produce a megaparsec-sized region with no detectable Ly-alpha absorption the intervening quasar has to be much brighter than Q0301-005.
