NSV 11749: Slow Nova or FU Ori Variable?

WILLIAMS D.B.

Abstract (from CDS):

Observations of NSV 11749 from Harvard photographic plates reveal that in 1899 this variable began to brighten gradually to 12th magnitude (blue), remained at maximum for four years, then gradually declined to 17th magnitude or fainter. The light curve alone is insufficient to determine whether this variable is a very slow nova, an FU Ori star, or possibly a unique type. Further photometry and especially spectroscopy are needed to classify this unusual variable.
