Sebastian F. Hönig (b. 1978) adroitly searched SOHO and NEAT images during 2000-2003 and was credited with 27 sungrazer comet discoveries and 479 minor-planet designations. However, his biggest thrill was the visual discovery of comet C/2002 O4 with a 0.25-m Schmidt-Cassegrain telescope on 2002 July 22.
Discovered on 19-9-2001 in Fountain Hills by Juels, C. W., Holvorcem, P. R.
