This star is classified as a UG with a range of 14.6-18.0p.
Since, 1 January 1993, there have been 2010 visual observations, BUT only 6 positive sightings.
4 have been around 18.0 which is minimum.
1 has been at 15.7, and was made by an expereinced observer. I note that on the night before and the night after, the variable was recorded at <15.7, and I suspect it should have been recorded at <15.7 as well.
1 has been at 13.0, again by an expereinced observer BUT no chart nor comparion stars are given and it was the only observation of this star by this observer.There is a 13.0 in the field and I wonder if this was mistaken for the variable.
I note that there have been 853 CCD observations, many of them positive at around 17.0-19.0 with some as bright as 16.3.
So I can't help but ask, what has happened to DE CNC? Can someone tell me why we are not seeing this star in outburst. I have searched the internet and can find very little useful information. Could it be a UGWZ?
