Abt, H. A. Abstract Spectroscopic classification is obtained for 169 northern A5-G0 stars predicted by Olsen (1979, 1980) to have abnormal spectra on the basis of Stromgren four-color photometry. The success in identifying reddened early type stars was nearly 100 percent, for Am and early type weak lined stars about 75 percent, for stars above main sequence about 50 percent, for composite spectra about 25 percent, and for Ap and Lambda Boo stars 0 percent. Thus photoelectric photometry is a successful first step in discovering stars of the more extreme spectroscopic abnormalities.
