Comet 6P/d'Arrest was magnitude 18.8, 104 million miles from Earth and had a very very short tail to the NW of the comet coma in these images. Comet 6P will make it's close approach to Earth in August 2021 at 69 million miles and will be at perihelion in it's 6.54 year orbit in September 2021 when it will be 125 million miles from the Sun but interestingly due to the geometry of it's orbit relative to Earth it will not brighten to magnitude 10 until November 2021.
