That and the fact that the outgassing on Triton was only observed when the probe was on top of it, NOT observed via telescopes on Earth. I repeat, as the ESO said, NO comet has been observed BEFORE PERIHELION outgassing out where Hale-Bopp was claimed to be outgassing so that McNaught could see it on his 1993 plate. The fact that this supposed outgassing ceased as the so-called comet approached the Sun stands as a second glaring reminder that this is not a comet, its a fraud.

Observations of dust
It has now been confirmed that a diffuse image found on a UK Schmidt plate obtained in April 1993 (IAUC 6198, 6202) is indeed of this comet (IAUC 6287). This shows that the dust production must have started already when the comet was at heliocentric distance 13 AU or possibly even before. This appears very unusual, and only a few comets have ever shown activity at this large distance (e.g. P/Halley at 14 AU). However, all such cases occurred after the perihelion passage; in fact, only comet Hale-Bopp has been observed at this large distance before perihelion.
