Comet C/2018 N2 (ASASSN) has developed a nice curved dust tail. I added sky vectors from JPL Horizons ephemeris to show the direction to the sun, the anti solar direction and the direction of the negative velocity vector to this image taken 2019-Aug-01 10:13:29 UTC.

These vectors are the position angles projected on the sky as seen by earth observers.

The curvature of the tail is toward the -v or negative velocity vector PsAMV.

C/2018 N2 (ASASSN) is now about 100 days prior to its 2019-Nov-10 perihelion at 3.125 au. While that is not particularly close to the sun, I think the tail should be quite delightful to image over the coming months and lengthen. Seiichi estimates a peak brightness of magnitude 10.5 near perihelion. Since the current earth distance is about 3.2 au and earth distance at minimum approach to earth is 2.2 au, I guestimate (swag) a tail lengthening by a factor x 1.5 in nice round numbers.
