Dear colleagues,

We detected that a dwarf nova PS Lac, an UGSS type with a range of
15.0-17.6 mag, in outburst at 15.4 mag on Oct. 7.58 (UT) from
Youichirou Nakashima's survey images with Canon 500-mm f/4.5 camera
lens + SBIG ST-8 in the course of the MISAO Project.

LACPS 20121007.57692 155C Mis
LACPS 20121007.57828 153C Mis
LACPS 20121007.57963 153C Mis

The last outburst seems to be on 2011 Oct. 1, just one year ago, at
15.66 mag reported from Gary Poyner.

Best regards,
