Notes

Listed in the late-type emission-line stars catalog of Allen (1973), which includes objects that may be either symbiotic stars or heavily reddened. Noted to be very red by Herbig & Kuhi (1963). Classified as a late-type giant (M7.5 III) without emission lines in Cohen & Kuhi (1979). Additionally, a nearby source might be associated with an X-ray source (Gaia EDR3 3219116509914971264; CXOJ054548.4-001236; 3XMM J054548.4-001236).
