We report the discovery of a new SU UMa-type dwarf nova,
Gaia18aak/ AT2018C, based on its optical observations, which were performed
at ve observatories (Lisnyky/Kyiv, Terskol, CrAO, Mayaki/Odessa and Star a
Lesn a, Slovakia) with six small telescopes. The observational campaign started
just after the alert was published by ESA Gaia, DPAC and the Photomet-
ric Science Alerts Team (http://gsaweb.ast.cam.ac.uk/alerts); the object was
very intensely observed during the rst month. After this there was organized
a four-month monitoring in order to test outburst activity of the object.
We detected the 0.0647-d (or 0.0692-d) superhump period during ve nights
of the superoutburst. Furthermore, we found the only possible outburst during
the subsequent 100 nights.
