ASASSN-V J175721.00+152502.1: NL?

   This object is a close double (common proper motion).

175721.008 +152502.01 (2000.0) Gaia_DR2_4501644012800425216 plx=1.073(0.052) dismod=9.8 pmra=-3.053(0.099) pmdec=-5.842(0.092) G=15.222 BP=15.334 RP=14.901

175720.816 +152505.61 (2000.0) Gaia_DR2_4501644012800888320 plx=0.995(0.061) dismod=10.0 pmra=-3.046(0.100) pmdec=-5.882(0.106) G=15.764 BP=16.229 RP=15.142

   The initial one is the variable and blue
(B-R=0.43), also 2MASS 175721.003 +152502.08 (2000.0) 14.344 14.174 13.824

Bright GALEX source:
NUV=15.536(0.015) FUV=15.702(0.026)

   The irregular variation appears to be more likely
NL-type (estimated M_V= +5.4 without correction for
extinction).  I couldn't find a period from the ASAS-SN data.
