Abstract: We report the discovery of a new SU UMa-type dwarf nova, Gaia18aak/ AT2018C, based on its optical observations, which were performed at five observatories (Lisnyky/Kyiv, Terskol, CrAO, Mayaki/Odessa and Stará Lesná, Slovakia) with six small telescopes. The observational campaign started just after the alert was published by ESA Gaia, DPAC and the Photometric Science Alerts Team (http://gsaweb.ast.cam.ac.uk/alerts); the object was very intensely observed during the first 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 five nights of the superoutburst. Furthermore, we found the only possible outburst during the subsequent 100 nights.
