We report on unprecedented short-term variations detected in the optical flux from the black hole binary system, V4641 Sgr. Amplitudes of the optical fluctuations were larger at longer time scales, and surprisingly reached ∼60% around a period of ∼10 min. The power spectra of fluctuations are characterized by a power law (∝ f, α ∼−1.7). It is the first case… CONTINUE READING
