 14 HDE 279088 (K2). The star photometrically seems like a luminous K1 giant. 
 14  AGK3 and PPM catalogs give the spectral class R0. However, we do not find 
 14  any indication in the literature that the star is carbon-rich. The Vilnius 
 14  diagram Qupyv,Qxzs, which is used for the identification of late-type 
 14  carbon-rich stars, also shows no indication of the carbon enrichment.
