Abstract: In this contribution we present observations of the symbiotic star BF Cygni during its current active phase. Our photometric monitoring indicated 1-mag bursts during 2015 and 2017 on the time-scale of weeks with gradual fading to the pre-outburst level for more than 1 year. During these events, our spectra show signatures of a variable mass-outflow and formation of a highly-collimated bipolar mass ejection.
