This is the comet Nishimura's final appearance captured amidst the twilight and haze. The comet is positioned about 3 degrees southeast of ζ Leo at the head of Lion, and due to the lack of visible surrounding stars, its exact brightness cannot be accurately estimated. However, it appears to be between 3rd and 4th magnitude. The tail extending towards the northwest can be barely discerned, but a clear image of it could not be captured.
View angle: 1.63×2.44°
