We obtained multicolor light curve of KR Aurigae on 23.02.2017 using 4 Bulgarian and Serbian
telescopes. We studied rapid variability in low state of the system for more than 5 hours. The
brightness amplitude was more than 2 magnitudes. The color indices and parameters of the
flickering source were estimated. The obtained temperature of about 30 000 K is considerably
above what we measured in other cataclysmic and symbiotic systems. We also searched for
short term periodicity of the brightness variations.
