Recently, brightness variations occurring on twice the accretion disk precession period in the old nova and permanent superhump system V603 Aql have been observed by Bruch & Cook (2018). In an attempt to detect a similar effect in other cataclysmic variables reported to contain permanent superhumps the novalike variable UU Aqr was observed during 11 nights in September 2018. While no traces of superhumps were seen in the data, rendering the quest for variations related to the disk precession period obsolete, the system exhibits regular variations with a period of ~4 days.

Bundesdeutsche Arbeitsgemeinschaft für Veränderliche Sterne e.V. (BAV), Munsterdamm 90, 12169 Berlin, Germany, www.bav-astro.de, publikat@bav-astro.de In this 76 compilation of BAV results, photoelectric observations obtained mostly in the years 2012 and 2013 are presented on 373 variable stars giving 524 minima on eclipsing binaries and maxima on pulsating stars. All moments of minima and maxima are heliocentric UTC. The errors are tabulated in column ‘±’. The values in column ‘O − C’ are determined without incorporating nonlinear terms. The references are given in the section ‘Remarks’. All information about photometers and filters are specified in the columns ‘Fil’ and ‘Rem’. The observations were made at private observatories. The photoelectric measurements and all the light curves with evaluations can be obtained from the office of the BAV for inspection. Please use the following link for an easy access to all the publications of the BAV including the “Lichtenknecker Database of the BAV”: http://www.bav-astro.de/sfs .
