Space.com says that those who have gotten up before sunrise to gaze into the twilight skies to see Comet Neowise have been greeted by the best comet performance for Northern Hemisphere observers since the 1997 appearance of Comet Hale-Bopp, emphatically ending nearly a quarter-century of lack of spectacular comets, and it’s only going to get better:
The first good opportunity for evening viewing begins on July 12, when the head of the comet will stand 5 degrees above the north-northwest horizon, 80 minutes after sunset (the end of nautical twilight). By July 14 its altitude will have already doubled to 10 degrees, and by July 19 it will have doubled yet again to 20 degrees up by the end of nautical twilight. By then it will have moved to above the northwest horizon.
So, we at Space.com feel that the best time to view the comet during the evening will come during the July 14-19 time frame.
We also strongly recommend that observers should seek the most favorable conditions possible. Even a bright comet, like this one, can be obliterated by thin horizon clouds, haze, humid air, smoke, twilight glow and especially city lights. We especially emphasize that last factor: the farther away you get from a metropolitan area, the darker your sky and the better your view of NEOWISE. Binoculars will enhance your view.
And more good news: No moonlight will brighten the sky, as the moon will be a waning crescent and visible only in the morning sky through July 20. On successive July evenings the comet will grow fainter, but it will be farther from the sun, setting later and visible in a darker sky. As we move into August, the comet will be very well placed for observers with small telescopes.
