Abstract
THE two total solar eclipses of this year are not attracting organised expeditions from Great Britain. The first one, on April 28, was annular over most of its path, though it was total along a narrow belt not more than half a mile wide from just north of San Francisco across Nevada and Idaho to a point north of Virginia City in Mon tana. The uncertainty in the position of the belt was esti mated at a quarter of a mile, and totality was nowhere longer than 1–5 sec. An eclipse of this kind may be valuable for the investigation of the flash spectrum at different levels, and observing parties went not only from the nearby observatories of Mt. Hamilton and Mt. Wilson, but also from the Allegheny Observatory. It is to be hoped that answers have been obtained to some of the problems which, with the aid of clouds, have been eluding eclipse observers for the past few years.
