I saw that on one of my photos and thought it was a lens artifact!

Nice! Care to share a picture you took?

71mb

I'll imagine it. /s

Psssht. That's not even that bad these days. Go try getting that file on a 14.4 baud connection.

If you want a lower file size you can champion support for JPEG XL so I don't have to choose between an insane 16bit PNG or a crushed 8bit jpg https://jpegxl.info/

I don't want a lower file size. I'll take quality any day. I just didn't want to wait for my poor mobile connection to load it this time.

JPEG XL would allow me to serve you the same quality at least twice as fast πŸ˜‰

Can anyone explain how this is the comet of the century?

Halley's comet happens every century. That's the baseline.

Looks like A3 is only visible once every 80,000 years due to its orbit. Earth will look very different by the time of returns!

From the article:

According to EarthSky, this comet (known colloquially as Comet A3, for obvious reasons) is special, as it’s the brightest to cross our planet’s sky in 27 years, leading some to dub it the Comet of the Century.

Huh, I'm pretty sure neowise had a lower magnitude. I was in a city at the time and could see it through the light pollution at night with the naked eye. This one disappears quickly in the dark after the sunset goes towards astronomical dusk... And the moon light is also making it impossible to see. Maybe looks brighter at sunset in specific parts of the world, but at least my experience in its glory was nothing like Neowise.

Also earthsky claims magnitude -5 to -7. I don't believe that. For context, the magnitude of Venus is about -4 and that planet outshined the comet greatly.

Agree. Could see neowise with the naked eye.

Maybe it's just the location of the comet in relation to the sun?

This one is like washed out until right after sunset and then it's gone past the horizon a few minutes later.
