On January 2 and 3 a small outburst was observed By Erik Bryssinck on comet 64P/Swift-Gehrels.  Despite the small amplitude  of the event it's trace is evident in the changing of the coma morphology. The Af[rho] quantity increased from about 160 cm to 290 cm in R band for measuring windows between 5,000 and 10,000 km. Below the images and plots made by Erik Bryssinck.
