A new three-point inverse solution using the α-β model reconstructs meteoroid masses and bulk densities from limited fireball observations, achieving 88% convergence on the EN catalog and producing a continuous density range of 300-4000 kg m^{-3} instead of discrete PE categories.

The 2023 February 27 fireball observed with ALIS_4D has a trajectory and orbit consistent with an Apollo-family asteroid parent body, with a computed strewn field along the Kiruna-Gällivare border in northern Sweden.
The paper estimates that in Antarctica up to 75% of finds in a new meteorite strewn field may be pre-existing meteorites, not from the witnessed fall.
