Title:  The Gran Telescopio CANARIAS Variable Star One-Shot Project

Stellar variability types are assigned on the basis of lightcurve appearance, which often remains unchallenged without further observational evidence. The VSOP (Variable Star One-shot Project) is a large international collaboration, which has so far obtained spectra of more than 1200 stars during the past few years using ESO facilities. Operationally this program is perfectly suited for a modern, efficient observatory, providing the 10,4m Gran Telescopio CANARIAS (GTC) with a large pool of filler observations. Scientifically, our aims are: (1) obtain first spectroscopy of all unstudied variable stars suitable for GTC, (2) generate an influx of serendipitous discoveries across all fields of astrophysics, (3) provide data products to the public in a fast and automatic way.
