Abstract

Six Mira variables, which were discovered at Harvard Observatory and lacked finding charts, were recovered on Maria Mitchell Observatory plates. We present accurate coordinates and updated light elements for CV Sgr, SW Sct, VV Sct, AO Sct, AV Sct, and BI Sct. AV Sct shows definite period changes during the time interval studied. SW Sct and AO Sct may also have experienced period changes.
