Kometu je pronašao 22. jula 2002. Sebastian Hoenig iz Nemačke, astronom osmatrač čije ime se često može naći na raznim html stranicama posvećenim kometama. Nakon više oblačnih dana počeo je da šara nebom svojim Schmidt-Cassegrain Meade LX-200 teleskopom od 10 inča (25 cm) i naišao na čudnu mrljicu u oblasti gde joj mesto bilo nije. Procenio je magnitudu pegice na 12 i komu na oko 2 uglovna minuta.
Za ovo otkrice je zapravo bio sasvim ne pripremljen. Uz sebe nije imao zvezdanu kartu, čak ni teleskop nije precizno 'useverio'. Položaj novog objekta je pribeležio na etiketi flaše za vodu i zatim kod kuće na nebeskim kartama proveravao da li na tom mestu postoji neki ucrtani objekat. Onda su usledili telegrami Central Bureau for Astronomical Telegrams (CBAT), pa neizvesnih nekoliko dana da se otkriće potvrdi.
Ovo je, kažu, prvo otkriće komete nekog Nemačkog amatera u poslednjih 60-tak godina.
Kometa će, kako se procenjuje, u naredna tri meseca biti dobra meta za osmatrače i sa malim teleskopima.
