This comet was deiscovered by the ASAS-SN skysurvey on 19 july 2017. This comet wasn't seen before but due an outburst was this object discoverd by the sky-survey.  After about a week there was again an outburst with a magnitude 1 brighter than before. Nice cvomet to observe and calculate the Af(rho) parameter.  Last observation is from  3 august 2017.  Comet is again slowing down.
