What's Happened To DX AND?
I note that there have been no reported confirmed outbursts of this star since early 2011. Although it has significant seasonal gaps, it seems a little odd to me that potentially multiple maxima might have completely escaped detection during this interval.
The same sort of apparent secession of activity seems to have been exhibited by both CH UMa and V493 Lyr in recent years, two stars that were observed as quite active during their early years under the AAVSO's program. As I recall, several other CVs I've followed over the years ave hinted at having such apparently extended dormant periods as well. It might be something worth looking into.
Just offered as an observation on my part.
