Seiichi Yoshida, MISAO Project; Nobuo Ohkura, Okayama, Japan; and
KenIchi Kadota, Ageo, Saitama, Japan, discovered a new variable star
MisV1023.

It was picked up by Yoshida from the candidates of new variable stars
detected by the PIXY system from images taken by Ohkura comparing with
images taken by Kadota. Kadota and Yoshida judged it as a real
variable star.

The magnitude are measured automatically by the PIXY system. Image
observers' names are noted after "Mis".

NSV 12608 is 3.1 arcmin from MisV1023. No star brighter than 14.8 mag
was detected at the position of NSV 12608. However, Dr. Brian Skiff
and John Greaves researched the chart in Nassau & Cameron, ApJ 119,
175 (1954) and revealed that MisV1023 is a new variable star.

The identification with the 2MASS data is by Taichi Kato.
