[en] Comet C/2001 A2 experienced several splitting events during its 2001 perihelion passage. The first break-up event was observed in March 2001 (IAUC 7616). In this paper we report the first results of our extensive imaging and spectroscopic monitoring campaign with ESO telescopes over several weeks before and after the perihelion passage on May 25 2001.
