COMMENT: A weak shock was observed in the solar wind around 18UT,
indicative of a glancing blow from a CME. At this stage this
is not expected to cause signifcant impact on the ionosphere.
However high to mid lattiudes may experience some depressed periods
over the next day if this event proves to be geo-effective.
