This star was first catalogued by American astronomer Frank Elmore Ross in 1925. Ross 154 was found to be a UV Ceti-type flare star, with a mean time between major flares of about two days. The first such flare activity was observed from Australia in 1951 when the star increased in magnitude by 0.4. Usually, the star will increase by 3–4 magnitudes during a flare.
