The authors discuss a redshift survey of the Corona Borealis region. Their unfilled deep survey consists of five probes complete to mR = 15.7. These cover 3.4 square degrees distributed over a ≡16.4 square degree region. The authors include redshifts, magnitudes, and positions for the 83 galaxies in this survey. A complementary filled survey covers 39.2 square degrees and is complete to mB(0) = 15.5. There are 37 galaxies in this survey, which is part of the CfA redshift extension (de Lapparent, Geller, and Huchra 1986). The combined survey provides further support for the "bubble-like" geometry revealed by the shallower CfA survey. The redshift distribution for the new survey is remarkably similar to the distribution in the neighboring Bootes region. The authors detect a void near Bootes with a radius ⪆ 13h-1Mpc (H0 = 100h km s-1Mpc-1). This survey also indicates that the structure of voids and surfaces in the galaxy distribution is insensitive to luminosity for MB(0) ⪉ -17.4.
