PRISMA (Prima Rete Italiana per lo Studio sistematico delle Meteore e dell'Atmosfera) is a collaboration initiated and coordinated by the Italian National Institute for Astrophysics (INAF) that counts members among Research institutes, Associations, Schools (the complete list of PRISMA members is available at www.prisma.inaf.it )

The project started with an All-Sky camera installed at the INAF Observatory of Pino Torinese Italy in cooperation with the existing French project FRIPON. In this way it was possible to test the real performance of the project having the goal to observe and record the fireballs, calculating their trajectories and orbits, reducing the uncertainty area where fragments can be find out before the possible contamination of the terrestrial environment.

Afterwards to the first test, seven camera were connected in the north of Italy within the end of 2016,
more other cameras were scheduled to be installed at INAF or Amateur Astronomical Observatories and
public facilities in order to cover a 100 km area among them.

Camera Specifications: Basler acA1300-30gm

CCD Sensor Sony ICX445
Frame Rate 30 fps
Resolution 1.3 Mpx (1296 px x 966 px)
Sensor size 4.9 mm x 3.6 mm
Pixel size 3.75 μm x 3.75 μm

The detection of fireballs for all PRISMA's camera is made thanks to the FreeTure (Free software to capTure meteors),
software developed by the FRIPON team under Linux-Debian OS and installed in the mini-PC connectged to the camera.

At the beginning of the year 2018 n.20 All-Sky camera were in operating status, so at this time
Sormano Astronomical Observatory received the request to join the project covering its area in the North of Italy.

The cooperation to the PRISMA project started in May 2018 when the All-Sky
camera has been installed and connected to the network in operative status.
