2019 Nov. 1-2 (5 comets)
I observed 5 comets visually on Nov. 1 and 2 in Kita-karuizawa, Gunma, Japan. In the evening on Nov. 1, it was almost cloudy. But fortunately, there was a gap of clouds in the southern low sky around the position of C/2018 W2. Around midnight on Nov. 1, the weather became fine with no clouds. The sky condition was excellent, so the comets and clusters and nebulae looked very well. On Nov. 2, the condition was bad through thin clouds. Mira, omicron Cet, looked very bright. I observed it on Nov. 1.595 (UT) as 3.0 mag with naked eyes. C/2017 T2 ( PanSTARRS )
C/2018 N2 ( ASASSN )
C/2018 W2 ( Africano )

2019 Sept. 9 (5 comets)
I observed 5 comets visually on Sept. 9 in Kita-karuizawa, Gunma, Japan. Just after a typhoon has passed, and the weather was fine. Two comets, C/2018 N2 and 260P, were very close, almost in the same field of view. I enjoyed the rendezvous. C/2017 T2 ( PanSTARRS )

I observed C/2018 N2 and C/2018 W2 visually on Aug. 16 in Kita-karuizawa, Gunma, Japan. Just after a typhoon has passed, however, there are many clouds. Hard to observe comets due to the strong moon light. C/2018 N2 ( ASASSN )
C/2018 W2 ( Africano )
