Comet NEOWISE is now a stunning sight in the NW evening sky! I urge anyone who has the chance to check it out - it's easily the most impressive northern hemisphere comet since Hale-Bopp in 1997. Binoculars are probably the ideal instrument to use. From a dark site (though competing with some aurora) I could make out a good 12 degrees of tail Monday evening, and faintly the ion tail. But even from the city the brighter part visible is well worth a look.
