Unfiltered CCD observations of Catalina OT J132900.9-365859 were done on two
nights between 4 and 6 April 2011 from CBA Klein Karoo / ex CBA Pretoria.
This transient is now around magnitude 16.5R. It is not visible on DSS-red
images (>20.5R), hence an outburst jump of over 4 magnitudes.
Superhumps with amplitude 0.45R (mean mini-max / range) are seen in the
light curve. The mean s/hump period over 24h was 0.07093d +/- 0.001
(estimated) with an 0.1R magnitude brightness drop over 24h.
This is very likely a faint outbursting dwarf nova of type UGSU.
