Last week North Next week

Best time and the azimuth, altitude (A,h) are at lat. 35 deg in the Southern Hemisphere. Azimuth indicates 0 for south, 90 for west, 180 for north, 270 for east.

C/2023 A3 ( Tsuchinshan-ATLAS ) It brightened up to -4.9 mag due to the forward scattering on Oct. 9 in the SOHO coronagraph images (M. Paradowski). It became a great comet of 0 mag on the ground. Now it is 6.0 mag (Oct. 30, Chris Wyatt). Fading rapidly. It will be unobservable soon in the Southern Hemisphere, or in January in the Northern Hemisphere. But it will be observable again in January in the Northern Hemisphere. Date(TT) R.A. (2000) Decl.

Although the brightness evolution almost stopped until mid October, a large outburst occured on Oct. 18 and it brightened up to 8.2 mag (Oct. 20, Martin Masek). It approached to Sun down to 0.008 a.u. on Oct. 28. It was expected to brighten up to 2 mag, or -4.5 mag at best. However, it completely disappered at the perihelion. It will be observable soon, but probably nothing remains. Date(TT) R.A. (2000) Decl.
