[vsnet-newvar 1687] Unknown Mira Variable at 03 58 05.87 +47 13 01.1 (2000)

[jg@jgws.freeisp.co.uk]

Seiichi Yoshida informed me of four suspected large amplitude red
variables on DSS images, noted during his researches, that were worthy
of further investigation.

A star at 03 58 05.87 +47 13 01.1 (2000) clearly shows marked variation
on four red plate images sourced via the USNOFS image and catalogue
server at www.nofs.navy.mil/data/FchPix/ , marked variation is also seen
on the four blue plates, and to a lesser extent variation is seen on one
of the far red plates in comparison to the other two, which are
overexposed.

Contemporaneous E (red) and O (blue) plates from the 1950s DSS1 survey
show the object to be far brighter on the red plate, and as already
noted the object is very bright on far red IVN plates.  It is also
likely an IRAS source.

This star is most likely a Mira.
