CSS J1220-10: fading from its first-ever outburst

This Catalina optical transient is fading from its first-ever 
outburst on 31 Mar.  We observed it also on 28 Mar, and 
confirmed that the outburst still continued.

Its color and fading rate during the outburst are reminiscent 
of dwarf novae in superoutburst. The outburst amplitude is, 
however, atypically small.
