REMARKS: THE 0620Z ERUPTION HAS PRODUCED A
DISCRETE AREA OF ASH NO LONGER CONNECTED TO THE
VOLCANO AND MOVING TO THE WEST SOUTHWEST AT 25
KNOTS.  A LARGER AREA OF FL140 ASH PERSISTS FROM
THE ONGOING AND EARLIER ACTIVITY.  THE HEIGHT OF
THE HIGHER ASH WAS PLACED AT FL450 DUE TO A PILOT
REPORT AND IS VERY DIFFICULT TO CONFIRM IN
SATELLITE IMAGERY.   ...

NEXT ADVISORY: WILL BE ISSUED BY 2005JUN11/1400Z
