The high-cadence search at 50 samples/sec of CR Dra revealed one B-band flare of 560 ± 30 seconds’ duration, and 30-mmag peak above the mean. Three additional potential low-level flares could not be confirmed. The search for fast sub-second flares was conducted with negative results. The study collected 1.15 × 107 photometric measurements over 64.16 hours on 27 nights from May 6, 2016, through October 25, 2016. This represents a flare rate of 0.016 flare/hour. The CR Dra binary has resolved orbital components with established orbital elements. From this flare and historical flare events, any correlation between the system components’ calculated linear separation and flare activity level could not be confirmed.
