Fireball radiant in Sanson-Flamsteed projection of equatorial coordinates from January 2016 to December 2019. The color scale corresponds to the initial velocity of the objects: (1) low velocities (in blue) for asteroidal like objects, (2)high velocities (in yellow) for cometary-like objects. The main showers are detected. Of the objects, 55% are sporadic: their radiants cover the sky uniformly except for its southern part, which is invisible from European latitudes. The north toroidal sporadic source is visible in the top left corner and low speed objects are shown along the ecliptic plane coming from the anti-helion source.
