New periodic comet discovered in 2016. It had been predicted to return in 2024. But actually, it returned much earlier than predicted. Now it is bright as 11 mag (Jan. 16, Giuseppe Pappa). It passed the perihelion on Jan. 25. In the Southern Hemisphere, it will appear in the morning sky in early February, then it stays observable in excellent condition after that. In the Northern Hemisphere, it will never be observable after this.
