[vsnet-alert 15005] V767 Cyg outburst again

[Seiichi Yoshida]

Dear colleagues,

We detected that a dwarf nova V767 Cyg is in outburst at 15.9 mag on
Oct. 7.52 (UT) from Youichirou Nakashima's survey images with 300-mm
f/2.8 camera lens + SBIG ST-8 in the course of the MISAO Project.

CYGV767 20121007.52406 159C Mis
CYGV767 20121007.52543 158C Mis

Well, I have reported the last outburst of this star on July 18 (as
below). So maybe this star tends to be in outburst frequently.

It was not visible at all on Nakashima's survey images on July 30,
Aug. 19 and Sept. 24.

Best regards,
