Abstract
Visual observations of the neglected Mira variable V407 Sco during the ten-year interval 1997 through 2006 provide a revised period and epoch for maximum brightness. The dates of maximum are represented by the elements JD 2453612 ± 401.5 (± 4 days) · E. The brightness range is from magnitude 10.2 to fainter than 14.5.
