PRISMA: A FIREBALL NETWORK FOR THE RECOVERY OF FRESHLY-FALLEN METEORITES IN ITALY

PRISMA (Prima Rete Italiana per la Sorveglianza sistematica di Meteore ed Atmosfera) is a fireball network dedicated to the observation of fireballs and bolides and to the recovery of freshly-fallen meteorites on the Italian territory [1]. The project started in 2016 as a partner of the international collaboration FRIPON [2]. PRISMA involves more than 60 institutes and it is coordinated by INAF, the Italian National Institute for Astrophysics. To date, the network consists of almost 70 all-sky cameras and has observed more than 2500 bright meteors. The observations and data analysis of PRISMA [3,4,5] allowed for the recovery of two meteorites, namely Cavezzo [6] (01/01/2020, L5-an, 55.3 g) and Matera (14/02/2023, H5, 117.5 g). At least other 8 fireballs observed by PRISMA between 2017 and 2023 were determined to be meteorite-droppers and with a predicted strewn-field over Italy. In this contribution, we will report on the finding, analysis and classification of the Cavezzo and Matera meteorites, and on the current status of the network operations.
