A new type of frequency dependence caused by an outgoing boundary condition has been found in the dispersion relation for ballooning modes. The new, simple dispersion relation has been found for the first time to give growth rates in excellent agreement with numerical results for small values of shear. The analytical stability condition has been improved.
