stars to avoid

Visually observed stars known to be constant or not measurably variable

The following is a list of stars present in the VSX catalog as of 2013 March 7 that are known or suspected of being constant and have been visually observed in the past.  You should not observe these stars anymore; if they are a part of your visual observing program, please remove them immediately.

The list is divided into three parts: named variables first, followed by NSV stars, and then a small number of GSC stars.  In the case of the GSC stars, these are primarily previously used comparison stars suspected of being variable at some time in the past.
