On more outburst took place in mid July, as the comet was reported to have a magnitude of 4.4 on 13 July, but by the end of the month its magnitude was reported to be about 7. No new fragment was detected after that outburst. Smaller outbursts of amplitude 0.4 and 0.2 mag were observed on July 25.0 and 30.0 respectively.

June indicated the presence of more fragments, named D, E, and F, near fragment B. Fragment D was separated on June 3.5 ± 1.8, fragment E on June 9.5 ± 0.7, and fragment F on June 11.3 ± 0.5, and resulted in an outburst. The successive fragmentation events in early June could explain the slow rise of the outburst, which lasted 8 days.

The closest approach to Earth took place on 30 June 2001, at a distance of 0.244 AU (36.5 million km; 22.7 million mi). On July 1 the comet had an estimated magnitude of 4.4–4.5 and its coma was estimated to be 16–20 arcminutes across. On 5 July two tails were observed, each
