  • The dates of the minima of Algol are one day early, commencing with the entry for Sun. Nov. 22, and continuing for the rest of the year (pages 53 and 55). Thus Algol will be at minimum on Nov. 20 at 14:01, Nov. 23 at 10:50, Nov. 26 at 7:39 and so on.
    
    It is to be noted that the numerical values of the time are correct, but that the minima occur a day later than listed for the last three entries of November and all of December. [Ref]

  • An error on page 64...The absolute magnitude M, of the star Ross 248, should be changed from 14.3 to read 16.3, and the luinosity L, from 0.0002 to 0.00002 times that of the Sun. [Ref]
  • Supposed error in the 1936 Handbook
