Abstract
SPECTRA OF STARS NEAR THE NORTH POLE.—In the Harvard College Observatory Circular, No. 180, we are informed that in the preparation of the revised Harvard Catalogue Miss Cannon has now classified the spectra of 110,000 stars covering more than one-half of the sky. As Prof. E. C. Pickering has received numerous requests for the spectra of stars near the pole the present circular contains a special list, prepared by Miss Cannon, of stars within 10° of it. All stars are included which have a magnitude in the Durchmusterung of 8.3 or brighter, and the table consists of three columns giving the number in the Durchmusterung, the photometric or Durchmusterung magnitude, and the type of spectrum. The number of stars included in this list is 825.
