C/2020 F3 (NEOWISE) comet was only just discovered in March 2020 by the NEOWISE space telescope. You have until the end of July to see it… but its traveling away from Earth so the sooner the better (I’m including a chart).
You can find it rising in the NNE morning sky around 4:30 a.m. near the constellation of Auriga and its brightest star Capella (check here for more info). It can be hard to see but with a clear sky it’s observable.
It won’t be back for another 6800 years so get out and take a look! And remember that light pollution makes these celestial events harder to see.
