   According to the ASAS-3 data, V1860 Sgr (previously reported
to be RCB: star, presently not considered to belong to this
type) shows relatively regular variations (amplitude 0.3 mag)
with a period of 40-50 d.  This periodicity is characteristic
to R CrB-type variations at maximum.  Although spectroscopic
observation is against the classification as an R CrB star, this
star probably needs more detailed examination.
