Abstract
NOVA LACERTÆ:—Several further notes on Nova Lacertæ appear in the Astronomische Nachrichten. In No. 4470 Prof. Pickering gives particulars concerning the earlier history of the star, according to the Harvard collection of photographs, and states that spectrum photographs by Mr. E. S. King showed eleven bright lines. Prof. Nijland gives the results of magnitude observations at Utrecht showing a gradual decrease in the nova's brightness from 7.40 on January 1 and 2 to 8.30 on January 16; the colour was fairly constant at 3.7, and is found to be similar to that of the long-period variables R Arietis, T Cassiopeiæ, and S Ursse, Maj. at their maxima. Photographic magnitude observations at Munich, reported by Dr. Kühl, agree with the above in showing a somewhat similar decrease over the same period
