Comet V-OBS (2019 Sept. 21): C/2018 W2

Hello everyone,
here is my latest comet observation:

C/2018 W2 (Africano):
2019 Sept. 21.89 UT: m1=8.9, Dia.=5.5', DC=3, 20x80 binoculars
[Diffuse, but fairly easy to see. Moon was just above the horizon and was not visible from the observing position, so it did not interfere the observation.]

The ICQ format is available on COBS https://cobs.si/.

Nice day to all.
