About this table: This table summarizes comets discovered and confirmed in SOHO satellite data. The Perihelion Date column represents the date at which the object reached its perihelion (closest approach to the Sun). The Comet Designation column represents the unofficial SOHO designation and also the official IAU designation. The Comet Discoverer column lists the person or persons who first reported the object. The Telescope column lists the SOHO instruments in which the object was discovered and/or observed. The Perihelion Distance column lists the object's closest approach to the Sun in units of AU (Astronomical Units). Additionally, the values are linked to the MPEC (Minor Planet Electronic Circular) that defines the official orbit for the object. The Orbit Updates column lists any subsequent orbit updates to the objects. Note that the majority of these links point to IAUC (International Astronomical Union Circular) files, which are only available to subscribers of CBATs Electronic Computer Service.
