Sighting in Semuy, February 24, 2019

The witness was watching television and used a commercial break to close the living-room shutters. Since a first sighting in 2016, they had made a habit of looking at the sky. Around 6:43 pm they noticed a point of light that kept changing color while staying in the same place. They took photographs, convinced that something unusual was going on. At 7:19 pm they ended the observation, feeling they had gathered enough evidence: 31 photos and 5 videos. No other witness account was collected.

The GEIPAN investigation concluded that this was a definite case of mistaken identity with the star Sirius. The phenomenon showed every characteristic of it: a long observation in good weather, a star-like appearance at normal magnification, and a bright object with colored twinkling. Sirius's position matched that of the phenomenon closely, with only a 1° difference in azimuth according to the testimony, and a consistent elevation. The witness put the elevation at 30°, but their sketch suggests it was probably around 15°. Sirius is also the only star to show such a wide range of colors when it twinkles, as seen in the photos and videos, and its low position near the horizon strengthens the twinkling. The case was classified A.
