SOHO Comet Discoverers' Totals

SOHO/Near-Sun Comet News and Views   |  My Hunt for SOHO Comets   |  A SOHO and Sungrazing Comet FAQ   |  SOHO Comet Links   |  My AstroWeb

This table lists the number of SOHO comets, including SWAN comets, discovered by each person, and it includes comets confirmed by CBAT/MPC and reported on MPECs (Minor Planet Electronic Circulars) and IAU Circulars, as well as those internally confirmed by SOHO personnel and granted a "SOHO number" (such as SOHO-500) while awaiting permanent designation. The numbers here will be in excess of the total number of confirmed SOHO comets (currently 1500, because some SOHO comets have been credited to more than one hunter, but should match the number of names in the "SOHO Discoveries" links on the Sungrazer Web site. Please report any discrepancies to me. Note that official credit for the discovery of SOHO comets goes to the SOHO spacecraft rather than the individuals who find them, although the finders are mentioned on the discovery MPEC bulletins.
