This paper is based upon observations carried out at the Observatorio Astronómico Nacional, San Pedro Mártir, B.C.N. México. They are of two types: (1) α(16)Λ(9)-photometry, obtained with the 1.5-m Johnson telescope, and (2) maps at the wavelengths of Hα and λ7751 A [Ar III] emission lines secured with the 2.1-m telescope.
