HadV62: = V1901 Sgr ?
K. Haseda reported the discovery of a new variable star (HadV62).
The amplitude suggests a Mira star, but the absence of the image on the
RealSky (confirmed by Haseda), likely identifications with the blue
Tycho2 (but missing on GSC) star, and the absence of an IRAS source which
is expected for this bright variable, is unusual
On the basis of the unfiltered CCD observation by Kyoto team, T. Kato
suggested it is a relatively red star
He also noticed
that HadV62 is possibly identified with V1901 Sgr
