Abstract
We report the detection of a large void (∼7 Mpc) between the redshifts 2.16286 and 2.20748 in the Lya forest of Tol 1038-2712. This void is centered near a foreground QSO Tol 1037-2704, which is at a distance ∼4.4 Mpc away from the void. We estimate the probability for the void to occur by chance in front of the foreground QSO to be a few times 10-3. We discuss the implications of the void being produced by excess ionization due to the foreground QSO.
