Photometry and spectroscopy of stars in northern H II regions
New UBV photometry of 60 candidates for the exciting stars of a sampleof optical H II regions between Galactic longitudes 30 and 70 deg ispresented, together with MK spectral types for a smaller number ofstars. These data allow the identification of 11 possible new excitingstars in 7 nebulae. A catalog of basic data on the 36 Sharpless (1959) HII regions in this longitude range has been compiled from the presentobservations and from a reanalysis of existing data and is alsopresented, with notes on individual nebulae.

Symmetric Galactic Nebulae.
