Absolute Magnitude is a discontinued, semi-professional science fiction magazine started in 1993 under the name Harsh Mistress. However, in 1994 after only two issues the name was changed to Absolute Magnitude. In 2002 the name was changed again to Absolute Magnitude & Aboriginal Science Fiction when the publishers acquired the rights to Aboriginal Science Fiction. Absolute Magnitude was published by DNA Publications and edited by Warren Lapine. Although it was supposed to be a quarterly magazine its actual releases were irregular. After releasing twenty-one issues under the Absolute Magnitude title (plus two as Harsh Mistress), the magazine ceased publication in March 2006.
