After all, this comet won't be back for 6,800 years, NASA says. 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. 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). After that, Neowise will likely get more faint as it moves away from the sun, Kramer said. That will also mean a much larger audience will be able to see it during "prime-time" viewing hours instead of having to awaken during the wee hours of the early morning. Evening visibility should peak this weekend according to astronomers. ![]() And only a few mornings later its altitude will have become too low to see it at all in pre-sunrise sky.īut as its morning visibility diminishes, there is good news: Comet NEOWISE will become prominent in the evening sky after sunset. By July 18, it will appear only 5 degrees above the horizon at the start of nautical twilight. NEOWISE reached perihelion - its closest point to the Sun - on 3 July 2020, and will make its closest approach to Earth almost 3 weeks later on 23 July 2020, when it will be passing us at a distance of 0.69 AU (103 million km).
