Light curve of comet 7P based on r-band photometry (blue circles). Purple triangles indicate an identified post-perihelion outburst, except for the outbursts of July 10 and 18, which are marked with green diamonds and yellow squares, respectively. The cyan dashed–dotted and pink dotted lines indicate the time of perihelion and closest approach to Earth, respectively. Red solid lines are third-order polynomial fits to the pre- and post-perihelion photometry used to identify candidate outbursts.
