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.
Taichi Kato pointed out that this object is identified with a planetary nebula PK32-3.1. The catalogued position of PK32-3.1 is 47 arcsec from MisV0701.
Taichi Kato pointed out that it is near by a planetary nebula PK 32-3.1 and influenced to the past observations of PK 32-3.1.
MISAO's observations, followed by TASS's observations, revealed that MisV0701 is a red variable.
In the past papers (Stenholm & Acker, MacConnell), PK 32-3.1 was noted that maybe it is not a planetary nebula because the spectrum was that of a red variable. But the spectrum was probably the mixture with a red variable MisV0701. The IRAS data is on the border between a planetary nebula and a red variable. That is probably the mixture of the two objects' characteristics, too.
