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.

Again, these stars should not be observed.  Please remove them from your visual observing program.
