Publications of the Astronomical Society of the Pacific
Photometric observations of Proxima Centauri between 0.3 /x and 5 /x show that this star has an effective temperature of 2700° K, a bolometric luminosity of 6.7 X 10 30 ergs sec -1 , and a radius of 1.3 X 10 10 cm, agreeing with the calibration of the faint end of the main sequence made by Greenstein, Neugebauer, and Becklin (1970) .
