On August 10, 2015, two people in Essonne observed a luminous object in the sky between 1 and 2 a.m. One of them took photos, although only one testimony was collected. The phenomenon, observed for about an hour, moved slowly and resembled a celestial body. It was confirmed that the star Arcturus was in the exact direction reported by the witness. However, the witness did not mention seeing Arcturus, which is puzzling. Weather conditions were unstable, with wind and pressure changes, which could explain the observed glow and colors. The photos provided little information due to motion blur and low brightness.
