We present a new formula for absolute magnitude determination for late‐type dwarf stars as a function of ( g – r ) and ( r – i ) for Sloan photometry. The absolute magnitudes estimated by this approach are brighter than those estimated by colour‐magnitude diagrams, and they reduce the luminosity function rather close to the luminosity function of Hipparcos.
