Comet NEOWISE has moved from the morning to the evening and now sets after the sun here in Southern California. However, it has become increasingly harder to spot from light-polluted Los Angeles, so this image was grabbed about an hour north of the city at 9:23 p.m. on July 16, 2020.

[This one’s also for Phil and for all the great moments we shared over the years. Like comets, memories may fade with time, but you, my friend, will always be remembered.]

Not since Comet Hale-Bopp in 1997 has a really bright comet graced our northern skies. That has all changed with the latest interloper to our neck of the solar system. Comet C/2020 F3, as it is known to astronomers, was discovered on March 27 by the NEOWISE space telescope. By tradition, comets are named after their discoverers, so this one is known to the rest of us as Comet NEOWISE.

As Comet NEOWISE approached the Sun, its orbital period was calculated to be about 4,500 years. But its encounter with the Sun’s massive gravitational field has now boosted its speed and increased its orbital period to about 6,700 years.

This photograph was shot from my back yard about an hour before sunrise at 4:49 a.m. on the morning of July 11. The comet is fading now as it moves away from the Sun, but it will always be remembered for brightening up an otherwise difficult year.
