Abstract
Peculiar M supergiants similar to VX Sgr and VY CMa are characterized by very red visual colours, a flux excess near 9,000 Å (I band) and a substantial excess longwards of 2µm (refs 1, 2). HV11417 has recently been reported to be the first similar star discovered in the Small Magellanic Cloud3. We report here the discovery of another star of this type, RG0044 – 2958, which is more unusual in that it is located at a distance of ∼2.5 Mpc, and is not associated with a detectable galaxy. It is probably the brightest star in a very low surface brightness dwarf galaxy in the Sculptor group.
