| contents | We report analysis of photometry and spectroscopy of a deep Algol-like minimum of the pre-main-sequence star WW Vul in July and August 2016. This revealed substantial reddening due to absorption by circumstellar material. After dereddening, our spectra of WW Vul were consistent with spectral type A3V throughout the event. Hα is normally in emission in WW Vul. During the minimum, Hα emission dropped by ~30% and FWHM of the Hα line reduced by ~15%. |
