ABSTRACT We present an analysis of long-term photometric variability for nearby red dwarf stars at optical wavelengths. The sample consists of 264 M dwarfs south of decl. = +30 with = 3.96-9.16 and MV 10-20, corresponding to spectral types M2V-M8V, most of which are within 25 pc. The stars have been...
