A. Biesecker, Emergent Information Technologies, Inc., and Goddard Space Flight Center, reports observations of nine additional Kreutz sungrazing comets detected by SOHO with the C2 coronagraph, with measurements by D. Hammer (the reductions and orbital elements by B. G. Marsden appearing on the MPECs specified below). Comets C/1998 J3 and C/1998 J4 were discovered by Hammer in a search of archival data. The remaining comets were found via the SOHO website by M. Oates (C/1998 K12, C/1998 K13, C/1998 K14, C/1998 K15); M. Boschat (C/2000 L4, C/2000 L5, C/2000 M1); M. Meyer and X. Leprette (C/2000 L4); J. Shanklin (C/2000 L5); and P. Shrekby (C/2000 M1). 1998 UT R.A. (2000) Decl.
