Image attached taken on 2022 Aug 31 at 13:50UT using a C11 RASA f/2.2 + Canon 6D. 5 mins. FOV 1 deg. North up. from Swan Hill, Victoria, Australia.

As well as an image taken remotely from Chile on 2022 Aug 30 at 08:47UT. ITEL T71 500 mm f/2.8 Takahashi Epsilon + CMOS. 5 min. FOV 30'. North up.

It is currently situated in Cetus, travelling south-westwards about 1 degree per day, and brightening.

The comet will be closest to Earth at 0.85 AU on September 25th, where it may peak at 10-11 magnitude, followed by a Sun approach of 1.59AU on November 28.

The orbit is Halley type with orbital period of about 94 years, retrograde.
