This unidentified flying object was accidentally immortalized by my daughter on holiday on July 23 2020 in a location in the Dolomites Alps in Italy, Meransen South Tirol.
The Dolomites, intended as an alpine section, are a mountain group of the Eastern Alps, located in Trentino-Alto Adige, Veneto and Friuli -Venice Giulia. A short video and some shots give an idea of the phenomenon. I highlighted the flight path with a circle. In another shot the object seems to be apparently metallic.
