Abstract:
    The photometric and spectroscopic observations of IRAS 18062+2410 =
    V886 Her, a candidate for protoplanetary objects, in 1996-1997 are
    presented. The star exhibits rapid light variations with an amplitude
    up to 0.3mag in V. A high-resolution spectrum of IRAS shows absorption
    lines of H, HeI, OI, FeII, SiII, NaI and other species, including
    [OII], [NII], and [FeII] that belong to the stellar envelope.
