All of that here in the inner solar system, and somehow ison is what we are supposed to be peeing our pants over?
Assuming that Ison is somewhere else because Hubble didn’t find it is a stretch.
The evidence is that ison is gone.

NICMOS on the Hubble is down. NEOWISE IS the ticket for infrared observations, even though its sensitivity is degraded. Incidentally, it was conveniently brought out of mothballs in September. Finding anything with the Sun as backdrop is tough as evidenced by previously unknown asteroids observed after flyby.
