* Astronomy

A terrific explosion which rocks Portland and neighboring cities early Sunday was identified Monday as a meteor, but definite conclusions may not be drawn for perhaps another year.
A wide variety of guesses - ranging from belief that a powder cache had exploded to hints of a bombing - narrowed down Monday to eyewitnesses accounts of a heavenly body streaking across the sky and disappearing to the northwest. Bend, Eugene and Portland accounts of the "fireball" apparently confirmed the meteor theory. Astronomical observers, however, pointed out it might be another year before the meteor, which apparently exploded in mid-air, could be found.
The explosion was believed to have taken place fifty miles northeast of Portland. Residents of Woodland, Wash., said a black cloud was observed rising out of the Cascades Mountains northeast of the community.
