Ice and Mixed Phase Clouds - Crystal with sector like branches

These crystals are typically formed at temperatures around -15C at supersaturations greater than those at which plates form, but less than those at which broad branched crystals (above) form. There is however a range of temperatures and supersaturations between about -13 and -17C at which these crystals may form.
