Briefly: I post on the PUNCH mission, since Sungrazing comets are relevant (including ‘comets’- asteroids passing so close to the Sun that rock vaporizes and emits). Now, PUNCH is relevant for (barely) tracking 3I/ATLAS as it starts going behind the Sun from our point of view.

”Comet 3I/Atlas is a fun challenge for PUNCH. We’re very
sensitive, though not a “telescope” (~2.5′ resolution: basically
naked-eye). At mag 12, the sky is *very* crowded. But we can
see Atlas and SWAN in nearly-raw data. We’re imaging at 4
minute cadence 24/7; FOV is 90° centered on the Sun.”
