Macroscopic Dark Matter Constraints from Bolide Camera Networks
  Macroscopic dark matter (macros) are a broad class of alternative candidates
to particle dark matter. These candidates would transfer energy primarily
through elastic scattering, and this linear energy deposition would produce
observable signals if a macro were to pass through the atmosphere. We produce
constraints for low mass macros from the null observation of bolides formed by
a passing macro, across two extensive networks of cameras built originally to
observe meteorites. The parameter space that could be probed with planned
upgrades to the existing array of cameras in one of these networks still
currently in use, the Desert Fireball Network in Australia, is estimated.
