摘要:
AbstractThe results of photoelectric and spectrographic observations of Nova Vul 1968 No. 1 are described. U, B, V magnitudes and colours ranging from 1968 April 18 to June 15 are given. The distance of the nova was estimated to 1450 ± 400 pc (m. e.). Its interstellar absorption amounts toAV= 1.2 ± 0.2 mag (m. e). Spectra were obtained between 1968 April 18 and May 8 and were used to measure radial velocities for two absorption system
