This is the second prominent member of the NGC 5866 group. As it is seen almost exactly edge-on, and is an extremely flat disc, it appears extremely elongated, shaped like a "knife edge". Supernova 1940A, which was discovered by Johnson, occurred in NGC 5907 on February 16, 1940 and reached magnitude 14.3 (see PASP 52, 146).
