YBa2Cu3O7 high temperature superconductor samples were weighed on an electronic balance during a warming cycle beginning at 77 degrees K. The experiment was configured so that the YBa2Cu3O7 material was weighed along with a magnet, a target mass, and liquid Nitrogen coolant. The weights were captured during Nitrogen evaporation. Results indicated unexpected variations in the system weight that appear as a function of temperature and possibly other parameters.
