REMARKS:    AROUND 0730Z THERE WAS A SIGNIFICANT ERUPTION
NOTED IN IMAGERY AND THE ASH IS EXPANDING IN ALL DIRECTIONS

MOTION TO THE NORTHWEST THROUGH EAST. AS THE ASH MOVES OUT
IT IS BECOMING FAINTER AND HARDER TO DETECT. DUE TO THE LACK
OF INFORMATION WE ARE ESTIMATING A MINIMUM HEIGHT OF THE
ERUPTION TO FL350. 

NEXT ADVISORY: WILL BE ISSUED BY 2003AUG29/1700Z.
