Discovery Information
Seiichi Yoshida, MISAO Project; Nobuo Ohkura, Okayama, Japan; and John Greaves, the United Kingdom, discovered a new variable star MisV1267.
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. John Greaves researched the NSVS data and confirmed the semi regular variation.

Special Notes
MisV1267 is recorded in the Hamburg-Bergedorf H-alpha Stars in Northern Milky Way as HBHA 18-40.
MisV1267 is also recorded in the carbon star catalogs as CGCS 719 = CGCS J0435+5250. Therefore it is a carbon star with H-alpha emission.
The MISAO Project observations suggest that MisV1267 is a Mira type variable with a period of about 400 days. The NSVS light curve shows a peculiar stagnation of brightening. The MISAO Project observations also suggest a hint of the stagnation.
Brian Skiff commented that H-alpha emission is kinda the usual thing for cool carbon stars. Brian Skiff also pointed out that MisV1267 is identified with a carbon star Kiso C5-213, and an emission line star VES 820.
