    "abstract": "We report the magnetic trapping of metastable $^3P_2$ atomic strontium. Atoms\nare cooled in a magneto-optical trap (MOT) operating on the dipole allowed\n$^1S_0-^1P_1$ transition at 461 nm. Decay via $^1P_1\\to {^1D_2}\\to {^3P_2}$\ncontinuously loads a magnetic trap formed by the quadrupole magnetic field of\nthe MOT. Over $10^8$ atoms at a density of $8 \\times 10^9$ cm$^{-3}$ and\ntemperature of 1 mK are trapped. The atom temperature is significantly lower\nthan what would be expected from the kinetic and potential energy of atoms as\nthey are transferred from the MOT. This suggests that thermalization and\nevaporative cooling are occurring in the magnetic trap.",
