STS047-151-643 Mt Spurr ash GMT 9/19 12:36:31. Mt Spurr, on the
northern end of the Alaskan Peninsula, erupted on September 17,
1992. The large ash plume was easily visible on environmental sa-
tellites, and started to move east from the mountain. Although
the STS047 south-looking attitude prevented the crew from viewing
the ash right after the eruption, they caught up with the long,
dark ash cloud roughly 2 days later. This photograph of the ash
cloud was taken over eastern Quebec and views west.
