Southern Eclipsing Binary Minima and Light Elements in 2020

摘要

We present 246 times of minima of 77 southern hemisphere eclipsing binary stars acquired in 2020. These observations were acquired and analyzed by the authors, who are members of the Southern Eclipsing Binary group of Variable Stars South (VSS) (http://www.variablestarssouth.org), using CCD detectors. For four of the systems we have derived updated light elements and present those as well as O-C values for the VSS minima. This paper is the sixth in a series by Richards et al.
