Abstract
The spectroscopic and photometric variability of CGCS 6107 has been studied with four telescopes from 2015 to 2018. The star varied between R=11.4 and 14.2 mag with a time scale of 500 days. An appreciable color variation was observed, the star being bluer when brighter. H emission was present around maxima. The spectrum is that of an N type giant veiled by a variable dusty envelope.
