[vsnet-chat 338] Re: V1830 Sgr comparison stars

[bas@lowell.Lowell.Edu (Brian Skiff)]

     Some fairly useless trivia about the V1830 comp stars:  the brightest
star is HD 166882, with an HD type of B9.  Vogt's UBV colors imply a somewhat
earlier type, near B5 or B6.  Houk does not provide an MK type for the star,
evidently from faintness or crowding.
     Taken at face value, the UBV colors of the second star imply an
unreddened mid-M dwarf.  Running the colors back along the standard reddening
line seems to make things progressively unlikely that it's a somewhat 
reddened K-giant.  There is no IRAS source or motion star in SIMBAD near
here.
