DDE 163 = 1RXS J185013.9+242222  (UGSU:)

Recent ASAS-SN Sky Patrol (Shappee et al. 2014ApJ...788...48S
and Kochanek et al. 2017PASP..129j4502K) data and light curve:

Rapidly fading – looks like the normal outburst 
of an SU UMa-type dwarf nova.
But watch out for a possible rebrightening!

Clear skies,
