Nebular Spectrum of Nova Aurigæ

Abstract

NOVA AURIGÆ faded away so steadily in March and April as to give little promise of soon again attaining any considerable brightness. All the more startling, therefore, was Mr. Espin's announcement of Mr. Corder's discovery that it had reappeared and that he himself on August 21 had seen it as a star of the 9˙2 magnitude with a monochromatic spectrum, presumably about 500 mmm. in wave-length.
