Now that we have everyone excited about the Mars occultation tomorrow, here is another exciting visitor from space putting on a show as we speak.

Comet C/2024 G3 (ATLAS) is closing in on the Sun for perihelion on Jan 13, 10:17 UTC.

Currently at mag -3.0, it will brighten to mag -3.6.

But it is difficult to observe from the Northern hemisphere. It will be difficult even after perihelion, assuming it survives this grazing trip around the Sun.

The best vantage point for observing Comet C/2024 G3 (ATLAS) is in space. Which is where astronaut Don Pettit took this stunning photograph from, perched with his camera behind a window in the NASA ISS at ~400 km altitude, on Jan 11.

Here is a still from a simulation of C/2024 G3 (ATLAS) by French optical engineer and amateur photographer Nicolas Lefaudeux.

The website shows a multi-day visualization of the comet as it survives perihelion and develops a bright tail that persists for several days thereafter.

Here is the latest image of the Sun's corona taken by the NASA/ESA SOHO spacecraft with Comet C/2024 G3 (ATLAS) in the view, 2 hours before perihelion.

The image was taken by the Large Angle and Spectrometric COronagraph (LASCO) instrument aboard the NASA/ESA SOHO (Solar and Heliospheric Observatory) spacecraft.

Did Comet C/2024 G3 (ATLAS) survive its close flyby of the Sun?

Perhaps, it did.

Here is an image of the Sun's corona taken by the NASA/ESA SOHO spacecraft with Comet C/2024 G3 (ATLAS) in the view, about 15 hours after perihelion.

The image was taken by the Large Angle and Spectrometric COronagraph (LASCO) instrument aboard the NASA/ESA SOHO (Solar and Heliospheric Observatory) spacecraft.

25 hours after perihelion, Comet C/2024 G3 (ATLAS) looks like a space plane headed for Earth with a large exhaust tail behind it, as seen in this image of the Sun's corona taken by the NASA/ESA SOHO spacecraft.

The image was taken by the Large Angle and Spectrometric COronagraph (LASCO) instrument aboard the NASA/ESA SOHO (Solar and Heliospheric Observatory) spacecraft.

One can see why Comet C/2024 G3 (ATLAS) will be difficult to observe from the northern hemisphere, given its location relative to the Sun as seen from a vantage point in the northern hemisphere.

Ideally, you want the comet to be located sufficiently above or below the Sun, but in the case of New York, it is located just slightly above the Sun for a few days and to the side after that.

Sydney OTOH has a much favorable view of the comet as seen below.

Comet C/2024 G3 (ATLAS) has finally arrived in the Southern Sky! 🤩 It’s clearly visible as a very bright object shortly after sunset at @esoastronomy Although the tail is still quite short, the comet is truly beautiful. We are so looking forward to capturing more tonight! For planning the composition, I used @planitphoto 👍
