The dust production (Afrho) of the comet C/2023 A3 has been dropping continuously in the last 6 months to reach a minimum. Afrho is finally rising again since one month.
C/2023 A3 혜성의 먼지 생성률이 6개월동안 감소하다가 한달만에 다시 증가하고 있다는 좋은 소식입니다.

The dust production (Afrho) of this dynamically new comet which was expected to be very bright at perihelion in October, has been dropping continuously in the last 6 months to reach a minimum of 4000 cm (when the comet was close to the 0 phase angle early May). Afrho is finally rising again since one month.
10월 근일점에서 매우 밝을 것으로 예상되었던 이 역동적으로 새로운 혜성의 먼지 생성(Afrho)은 지난 6개월 동안 지속적으로 감소하여 최소 4000 cm에 도달했습니다 (혜성이 5월 초 0도 위상각에 가까웠을 때). Afrho는 마침내 한 달 만에 다시 상승하고 있습니다.
