Аннотация: In this paper, details of the detection of new object MASTER OT J044907.58+705812.7 (AT2024aaf) discovered on January 14, 2024 during a regular survey using the MASTER-Tunka telescope of the MASTER Global Network of Moscow State University have been present. Additional photometry of the object during joint observations at AZT-11 and 2.6-m ZTSh telescopes of CrAO RAS, MASTER-Tunka, and MASTER-Kislovodsk telescopes has been obtained. Large amplitude(>7m), blue color at maximum, brightness fluctuations during the flare with a characteristic time of ~0.06 days, long (at least 50 days) return to a calm state, the presence of at least four repeated rebrightenings gives grounds to classify the object as a dwarf nova of the WZ Sge type with multiple rebrightenings. In the paper, details of the detection of flares of other dwarf novae: MASTER OT J195416.74+494421.1, MASTER OT J150719.46–283114.9, MASTER OT J185835.32–354042.2, MASTER OT J174714.38+150048.1, and MASTER OT J065054.42+593625.5 as an example of the operation of software for processing wide-field images and identifying new and variable sources in them in real time have also been provided.
