Abstract
Very red optical and IR-color indices indicate the presence of a dense circumstellar shell around object FBS 2213+421. The estimated total mass-loss rate is typical for dust-enshrouded oxygen-rich Asymptotic Giant Branch (AGB) Long-Period Mira-type variables. K-band monitoring is necessary to determine the pulsation period, the absolute bolometric luminosity, and the distance to this object.
