* Discovery Information

It was detected by the PIXY system as one of the candidates of new variable stars from images taken by Ken-ichi Kadota, Ageo City, Saitama, Japan, then confirmed by Seiichi Yoshida.

DZ Ser (peculiar nova in 1960) is 2.1 arcmin from this object, but probably this is another object.

* Special Notes

Taichi Kato pointed out the possible identification with DZ Ser, a nova in 1960. Kato commented that DZ Ser is a 14-mag nova discovered in spectral observations. The position is very different on some papers as follows.

  Duerbeck             175812.72 -103350.35 (1950.0)
  Wyckoff and Wehinger 175812.8  -103400.5  (1950.0)

However, Seiichi Yoshida revealed that it is found as a faint star on the DSS 1 and DSS 2 images, and it looks brighter on R-band image. So it will be a red variable.
