arrived in the inner solar system from behind the sun from earth's perspective and just below the plain of the solar system. As a result it wasn't viewable favorably for the northern hemisphere, and didn't brighten until it was already hugging to close to the sun to be appreciated much from the Southern Hemisphere. C/2020 F3 NEOWISE is rounding the sun very close, and was just recently viewable in SOHO's Coronagraph. Because it's been so close to the sun from earth's perspective it's basically impossible to see without special telescopes right now,[Update, As of July 5th, people are spotting the comet in the morning sky from the Northern Hemisphere]...like SOHO. A comets brightness is a function of how close it gets to the sun, how much water vapor and cyanogen and other gases escape, and then how close it is to earth. In this case, It's going to be bright because of how close it's getting to the sun, and it never really gets all that close to earth as far as comets go. So it's going to dim very quickly after leaving the suns vicinity.

However there should be at least a narrow window where NEOWISE might be visible to the naked eye. , in the evening twilight sky, in the northwest by mid July. (DAMMIT) It's going to be tricky at first. For people in the northern hemisphere, the glare of twilight is going to keep this comet difficult to spot. NEOWISE will be as bright as magnitude 1 or 2 early on, Or for comparison, that's roughly the brightness of most of the stars in Orion. While that's pretty bright, it's no match for evening or morning twilight, Still it might be worth checking out.

I'm going to go out on a limb and say around July 6th or so is when it should start to be a good time to look about an hour after sunset. And if you are a morning person, There may be a few days in July between the 6th and about the 14th where you might be able to spot it in the northeast during morning twilight. That said, it may become visible a bit earlier or later in the month depending on brightness. Unfortunately most of the stars in the vicinity of C/2020 F3 NEOWISE are going to be hard to spot as well, so the hope is, you'll just be able to find a smudge low in the sky in the northwest an hour after dark. NEOWISE is escaping the sun, so your best bet is to look just above the brightest part of the sky and see if you can find it.

Now while NEOWISE in reality will be shades of white and light green, any brighter object like a setting moon, distant lightning, or clouds visible just above the horizon or nearly lost in evening twilight is going to appear a bit rusty colored, just like Panstarrs did in 2013. So NEOWISE isn't special in that regard. If you live in the far north, and not so far north that the sun doesn't set for a couple hours in July, you may have a unique opportunity to watch NEOwise in the Northern sky from dusk until dawn.
