I'm currently working on a journal paper about the comets of 2019 (it was a poor year for visual comets), and have also been processing recent BAA observations in COBS for sending to TA. A point arises from this, which I only spotted when applying an aperture correction:
It appeared as if a few observers had been using telescopes in the 1 to 3 metre class! Whilst these would be nice to have, I suspect that they are actually a tenth the size. COBS (and the ICQ format) has the aperture in centimetres, so for example a 200 mm SCT would go in as 20.
A few observers left justify the f number of their telescope - it should be right justified, although this is not clear in the ICQ guide at https://cobs.si/help?page=icq_format I think the issue will only arise if you manually format your observations.
Some of the comets at perihelion in 2019 are still under observation by imagers, but all are too faint for visual observation, so I will probably close the book in the New Year and submit the paper then. Late observations can still be incorporated at the review or proof stage.
I'm not sure when we will get another readily observable visual comet. As mentioned on the comets-ml 2020 P1 (NEOWISE) was brightening quite rapidly, but whether it will survive perihelion is another matter. If it does it could be visible in the morning sky from around October 20, though the observing window is short and it fades rapidly.
