Comet C/2023 A3 (Tsuchinshan-ATLAS)

[Weather-history]

This has become of interest after this comet  was discovered by a South African Observatory last month. It won't reach perihelion until 28th September, next year and closest to Earth around the 13th October 2024 at about 0.5 AU .

Speculation is that it could become a naked eye comet, so watch this space over the next few months.

Possible -3 mag from forward scattering would be something. Always tricky predicting comets this far out as they go wrong

A little comparison to other comets I've pinched from comet group on groups.io

C/2023 A3 is currently magnitude ~18 at over 7 AU from the Sun

Comet Hale-Bopp was discovered at magnitude 12, 7 AU from the sun, and reached perihelion at 0.9 AU out.

Comet ZTF was discovered at magnitude 17, 4.5 AU from the Sun, and reached perihelion 1.1 AU out.

Comet NEOWISE (2020 F3) was discovered at magnitude 17, 2 AU from the Sun, and reached perihelion 0.3 AU out.

Comet McNaught (2006 P1) was discovered at magnitude 17, 3 AU from the Sun, and reached perihelion 0.17 AU out.
