      A dark starfield is shown with a dim green blur in the middle. Faintly   
      extending from the green blur is a tail toward the left. Please see the   
                    explanation for more detailed information.

      Explanation: Will Comet Nishimura become visible to the unaided eye?   
      Given the unpredictability of comets, no one can say for sure, but it   
      currently seems like a good bet. The comet was discovered only ten days   
      ago by Hideo Nishimura during 30-second exposures with a standard   
      digital camera. Since then, C/2023 P1 Nishimura has increased in   
      brightness and its path across the inner Solar System determined. As   
      the comet dives toward the Sun, it will surely continue to intensify   
      and possibly become a naked-eye object in early September. A problem is   
      that the comet will also be angularly near the Sun, so it will only be   
      possible to see it near sunset or sunrise. The comet will get so close   
      to the Sun -- inside the orbit of planet Mercury -- that its nucleus   
      may break up. Pictured, Comet Nishimura was imaged three days ago from   
      June Lake, California, USA while sporting a green coma and a thin tail.
