AG Draconis is a strongly interacting binary system which manifestscharacteristic symbiotic activity of alternating quiescent and active stages.The latter ones consist of the series of individual outbursts repeating atabout a one-year interval. After seven years of flat quiescence following the2006-2008 major outbursts, in the late spring of 2015, the symbiotic system AGDra started to become brighter again toward what appeared to be a new minoroutburst. The current outburst activity of AG Dra was confirmed by thefollowing three outbursts in April 2016, May 2017 and April 2018. Thephotometric and spectroscopic observations suggest that all these outbursts areof the hot type. Such behaviour is considerably peculiar in almost 130-yearhistory of observing of this object, because the major outbursts at thebeginning of active stages are typically cool ones. In the present work, thecurrent peculiar activity of the symbiotic binary AG Dra is described indetail.
