- Аннотация: Photometric and spectroscopic observations of the rapid variable Ae star WW Vul were carried out in April - October,1983. Within the observational period the equivalent widths of Hα emission were varying 15 times, whereas the brightness of the star remained constant. The radial velocity of absorption of the Hα two-component profile has been varying from 0 to -140 km/s.
