* Discovery Information

Seiichi Yoshida, MISAO Project; Nobuo Ohkura, Okayama, Japan; and Ken-ichi Kadota, Ageo, Saitama, Japan, discovered a new variable star MisV1340.

It was picked up by Seiichi Yoshida from the candidates of new variable stars detected by the PIXY system 2 from images taken by Nobuo Ohkura and Ken-ichi Kadota, and confirmed by Ken-ichi Kadota.

This is a new Mira type variable adjoining to a Mira type variable V2010 Cyg = LD 162. MisV1340 is a northern component of double stars with similar brightness lying north-south direction with a separation of 20 arcsec, and the southern component is V2010 Cyg.

We once judged the identification of V2010 Cyg was wrong and reported it as the revision of V2010 Cyg's coordinates [vsnet-id 299]. But based on our further researches, we concluded both of the double stars are variable and announced the northern star as a new variable.

Please read the following report in details:
