GSC1567.2095: new bright dwarf nova

   ASAS-SN light curve:


   Blended with nearby stars.  The true amplitudes should
be larger.  Outbursts with different amplitudes tend to
alternate.  Type UGSS.  Outburst intervals: 13-28 d.

   The object is registered as
180840.9 +161442 (2000.0) ASAS180841+1614.7 MISC 11.95V (0.18) P=26.744007 
as a blended object (the location points to the brightest source).
The true variable component is the middle blue object.
To avoid ID ambiguity, the use of the ASAS variable name
would better be avoided.

180840.219 +161430.58 (2000.0) Gaia_DR2_4498953679650565888 plx=1.978(0.055) dismod=8.5 pmra=-3.888(0.120) pmdec=-18.310(0.106) G=15.616 BP=15.919 RP=15.096

   Nearby object.  Outburst maxima around M_V = +4

NUV=16.442(0.023) FUV=16.623(0.038)
