We present Hubble Space Telescope Observations of (596) Scheila during its recent dust outburst. The nucleus remained point-like with absolute magnitude HV = 8.85 ± 0.02 in our data, equal to the pre-outburst value, with no secondary fragments of diameter ≥100 m (for assumed albedos 0.04). We find a coma having a peak scattering cross section ~2.2×104 km2, corresponding to a mass in micron-sized particles of ~4×107 kg. The particles are deflected by solar radiation pressure on projected spatial… CONTINUE READING
