Gaia20dsz: superhumps detected during a new superoutburst

According to the data from TRANSIENT Name Service (TNS), Gaia20dsz/AT 2020rgw was discovered on 2020-08-12 06:36:00.000 by S.T. Hodgkin, E. Breedt, A. Delgado, D.L. Harrison, M. van Leeuwen, G. Rixon, T. Wevers, A. Yoldas (IoA Cambridge), N. Ihanec, K. Kruszyńska, K.A. Rybicki, Ł. Wyrzykowski (Warsaw University Astronomical Observatory), Z. Kostrzewa-Rutkowska (Leiden Observatory), D. Eappachen (SRON/RU), G. Marton (Konkoly Observatory), on behalf of the Gaia Alerts team.

Using our Outbursts Alerting System, we predicted the next superoutburst to occur within MJD 61309-61324.

Time-resolved photometric observations were obtained using the 0.5-m OAUJ Cassegrain Telescope, the 0.6-m Cassegrain telescope at the Astronomical Observatory of the University of Warsaw in Ostrowik, the 0.4-m telescope of the EEye Astronomical Complex and the 0.7-m f/4 AZT-8 telescope at the Observational Station Lisnyky of Taras Shevchenko National University of Kyiv. The results were published in The Astronomer's Telegram.
