Comet C/2021 A1 (Leonard) imaged on November 11th, 2021, since my previous image a week ago the comet has increased its brightness from magnitude 10 to 9.5 so it is already observable with small telescopes. Regarding morphology, its coma has grown from 9' to 11' in angular size, while the tail has been extended from 16' to 19' in length with a narrower and sharp jet to antisunward direction.
