A meteor flew over Sardinia and Corsica in the night between 23 and 24 May . Two those that lit up the Italian skies last night, a first fireball was sighted from Tuscany to Veneto.
Documenting its passage were the instruments of Prisma, the First Italian Network for the Study of Meteors and the Atmosphere of the National Institute of Astrophysics (INAF).
The fireball that flew over the island was filmed by the two Prisma cameras from Sardinia, Sardinia Radio Telescope and Gennargentu , plus a Fripon camera from Corsica.
"The image taken from the Gennargentu room is truly spectacular and shows the trail of the fireball that crosses the whole sky, passing almost to the zenith ", underline the experts. The meteor was imaged starting from an altitude of 85 kilometers, when it had a speed of about 20.5 kilometers per second, and extinguished at 44 kilometers with a speed of 16 kilometers per second, with a duration of almost 8 seconds.
Given the high final velocity, the entire meteoroid was destroyed in the re-entry phase. Projecting the trajectory on the ground, it moved from north-east to south-west, with its starting point on the Tyrrhenian Sea and its final point near Villanova Tulo, in the Sarcidano area.
