Southern hemisphere

Not visible to typical instruments. Current estimate mag 18.1. Historic peak was mag 13.5. Visual and most CCD amateur setups will not see it. Space telescopes or large ground telescopes are the remaining path.

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.
