- Аннотация: Photoelectric UBV observations of the infrared source IRAS 18062+2410 = HDE 341617 were first carried out on 38 nights in 1995. Night-to-night light variations with an amplitude as large as 0.(m)4 were detected. The colors corrected for interstellar reddening suggest that the star is most probably of spectral type B5 I. Spectroscopic observations lend support to the B classification of the star and reveal the presence of strong Ra emission in its spectrum. The current spectral type of HDE 341617 disagrees sharply with its estimate (A5) given in the HDE catalog. Analysis of the photographic collection of the Sternberg Astronomical Institute Sky Patrol indicates that in the first half of this century the star was, on average, almost 1.(m)5 brighter than at present.
