CometClass Ecatalogued
Unknown

Not currently visible. Last report 2096 days ago at mag 21.6. Historic peak was mag 17.4. Typical backyard telescopes will not show it. HST, JWST, or an 8–10 m class telescope might recover it with a good ephemeris.

COBS peak mag 17.4 on 2028-11-03 · perihelion 2028-11-05. Window is those dates ±3 days — not a light-curve fit.

Light curve

Brightness over time (V mag)

Gold = reported observations. Steel dashed family = ensemble (nominal / outburst / fade / disruption).

Tail length

Converted to degrees from COBS (d / arcmin / arcsec). Empty until analysis has pulled the archive.

Ensemble is a first-pass H0/n photometric model plus observed samples — not a trained ML forecast yet. The background analyzer walks the catalog one object at a time so COBS is not flooded. Disruption track rises after perihelion to stand in for solar-wind stripping.
