C/2024 G3 ( ATLAS ) It approached to Sun down to 0.09 a.u. on Jan. 13. It brightened up to -2 or -3 mag and it was detected even in the daylight. The nucleus was disintegrated on Jan. 19. However, its remnant is still visible. Now it is 8.5 mag (Feb. 23, Marco Goiato). Fading rapidly. In the Northern Hemisphere, it will never be observable after this.
