    Abstract

    THE NEW STAR IN AQUILA.-The new star in Aquila has continued to decrease in brightness at about the same rate as Nova Persei of 1901. On June 21 and 22 it was observed to be about 3rd magnitude, and its reddish colour had become quite pronounced. Prof. Fowler found that the hydrogen lines were still very brilliant on these dates, and that the most remarkable change since June 16 was the appearance of a broad bright band in the blue, about A 464. The enhanced lines of iron in the green were visible, and also the group of bright and dark lines about the position of D. There was also a dark line near A615, which had not been noted in the earlier observations, and the continuous spectrum had diminished in brightness. The principal features of the spectrum were readily observed with a Zollner star spectroscope on a 3-in. telescope.
