Thanks for the link. I'm typing this at 11:43pm in Cupertino, CA. I plugged in Cupertino as my location, and it says Rise is 5:02, which I assume means 5:02 am

Thanks for the link. I'm typing this at 11:43pm in Cupertino, CA. I plugged in Cupertino as my location, and it says Rise is 5:02, which I assume means 5:02 am, which makes sense. However, it also says VISIBILITY RIGHT NOW C/2023 P1 (Nishimura) is above the horizon from California, United States edit_location_alt. Right now it is placed in the East-North-East direction at an altitude of 23° above the horizon. How can it be visible and above the horizon right now if the rise time is 5:02am?

Honestly I don't know. My guess would be some kind of bug resulting from integrating different, conflicting data sources? But I'm mostly responding so that someone who knows better sees their bat sign and doesn't wait to see if I respond.

In general, you can only expect the interval between the rising and setting of a celestial object to be similar to that for the sun on that day if the object is near the ecliptic. Perhaps the most obvious counter-example is the pole star, which, being closely aligned with Earth's axis, never sets on Cupertino. According to the same site, however, the comet is currently in Leo, which is close to the ecliptic and is currently setting before the sun, so I cannot see this being the explanation here.
