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.
