Abstract

We report photometry of the novalike variable MV Lyr during the enormous outburst seen in 1997. We observed quasi-periodic oscillations with typical periods of 19, 29, 47 min, light variations at 0.1294 days (or its 1-day aliases) and amplitude [FORMULA], and flickering consistent with a shot-noise model.

Key words: stars: oscillations – stars: novae, cataclysmic variables – stars: individual: MV Lyr – stars: flare – stars: binaries: close – stars: activity
