At that time it was a 10th magnitude comet, located {{convert|2|AU|e6km e6mi|abbr=unit|lk=on}} away from the Sun and {{convert|1.7|AU|e6km e6mi|abbr=unit|lk=off}} away from Earth. The comet is notable for being one of the brightest visible to observers in the northern hemisphere since [[Comet Hale–Bopp]] in 1997.<ref>{{Cite web|last=Siegel|first=Ethan|title=How To See Comet NEOWISE, Earth's Most Spectacular Comet Since 2007|url=https://www.forbes.com/sites/startswithabang/2020/07/13/how-to-see-comet-neowise-earths-most-spectacular-comet-since-2007/|access-date=2020-07-13|websi
