On the mass and size of the Spanish fireball
CNEOS says
Velocity (km/s) 40.4
Total Radiated Energy (J) 3.7e10
Calculated Total Impact Energy (kt) 0.13
0.13 kt is 5.4 x 10^11 J
1 kg at 40.4 km/s has 8.16 x 10^8 J
So, that CNEOS impact energy corresponds to a mass of 666 kg.
At 2300 kg/m^3 that's 0.4 m radius or 0.8 m diameter.
So, a beachball.
