This object was discovered by Huruhata, renowned for the discovery
of EG Cnc. The V591 Cen discovery article wrote:
"Only one maximum has been observed. Positive observations
are as follows"
(If the mags 15.8-16.0 represent combined mags, the rest of the data
strongly suggest a superoutburst. Time-resolved photometry during
the current outburst is very strongly requested).
Correct position of V591 Cen from Berto Monard during the 2006 outburst.

The actual position (2000) of the probable CV, V591 Cen, based on
astrometry on an outburst image gave:
12 42 17.95 -33 34 07.1 (vs UCAC2) with positional uncertainties of
0.03 and 0.15 respectively.
This is 2.3"N and 2.2"W of the previously assumed counterpart which has
position end figures: 18.12 and 09.4 .
The CV atlas considers V591 Cen as a non-cv based on spectral
measurements performed on this incorrectly assumed counterpart.
The brightness of V591 Cen on the above image (unfiltered CCD) was
15.5CR (UT 2006 nov30.1).
The object is not shown on DSS2-red to a magnitude limit of well
