Spectral survey of 245 galaxies with mB⩽17.5 in the narrow strip {+28° 20′>DEC>+28°10′, 15h28m0>R.A>10h42Mm0} confirms a bubble-like type of the large-scale structure around the coma supercluster, have been founded by Lapparent et al. (1986). A correlation function in the volume has the power index γ=1.5 and the correlation radius rO= 29 Mpc (H=75 Km/s Mpc). For the sample of 14 voids their mean diameter <DV> equals to (33±3) Mpc. This value coincides with the correlation scale rO= 32 Mpc for Abell clusters, and also with the mean length of “God finger” for a rich cluster, 2√ 3σvH−1 = 32Mpc. We note a presence of a preferential orientation of voids toward the Coma supercluster, <Dvrad>/<Dvtan>= 1.15±0.8, that corresponds to a possible peculiar flow toward/outward Coma with Vpec∼400±200 (Km/s) at a scale ∼100 Mpc.
