COMMENT: The ionosphere appears fairly stable after the CME/weak
shock passages recently and the enhanced geomagnetic conditions
from prolonged IMF Bz. The high latitudes will should remain
disturbed due to ongoing IMF Bz southwards. The oncoming coronal
hole should disturb the ionosphere in coming days.
