J/A+AS/70/481 J/A+AS/70/481 An atlas and catalogue of northern dwarf nova A Bruch F J Fischer U Wilmsen Astron. Astrophys. Suppl. Ser. 70 481 1987 1987A&AS...70..481B dwarf novae finding charts novae, cataclysmic variables positions An atlas of 90 northern dwarf novae (delta greater than 20 deg) is presented. It is meant to supplement the Atlas of Southern and Equatorial Dwarf Novae of Vogt and Bateson (1982). Together, these publications represent a comprehensive collection of dwarf nova finding charts for the whole sky. In addition to the atlas, coordinates are given for most of the dwarf novae with accuracies significantly higher than published hitherto. (See J/A+AS/93/463 for the Southern Part)
