Abstract
A LARGE SUN-SPOT.—On Saturday last a very fine spot was visible near the sun's eastern limb, having evidently been brought into view by the sun's rotation. Its full magnitude was revealed a few days later, when the foreshortening was reduced. Changes in the umbra and bright bridges crossing it were detected in the course of a few hours. The spot will be well worth watching during the remaining period of it visibility, especially as many years may perhaps elapse befort observers are favoured with another spot of similar size.
