C/2022 E3 (ZTF)

C/2022 E3 (ZTF) is a long-period comet from the Oort cloud that was discovered by the Zwicky Transient Facility (ZTF) on March 2, 2022. The comet has a bright green glow around its nucleus, due to the effect of sunlight on diatomic carbon and cyanogen. It’s closest approach to Earth was on February 1, 2023, at a distance of 0.28 AU (42 million km; 26 million mi).

Open Cluster NGC 1647 in Taurus and Comet C/2022 E3 (ZTF)

I know I am kind of late to the party. But in my defense: When I checked where the comet was in the sky when I first heard about it, it was in the north, and my house was blocking the view. I didn't realize that it will be coming around to the south where I can image it.

Here is the location and future path of comet C/2022 E3 (ZTF) in the night sky, as seen from the U.S. on Feb 13 around 9:30 p.m. mountain time, facing south.

Comet C/2022 E3 (ZTF) is dimming rapidly, currently at magnitude > 7.
Current distance from earth = 0.483 au = 72.25 million km.

Here is a gorgeous composite image of the departing comet C/2022 E3 (ZTF) along with planet Mars taken two nights ago.

The broad white dust tail and the long narrow blue ion tail are clearly visible. The coma shines brightly in green color at 518 nm wavelength, emitted by C2 (dicarbon) atoms.

In the foreground is the Matterhorn, a mountain in the Italian Alps with a picturesque peak.

Where to see comet C/2022 E3 (ZTF) in the night sky from central U.S. tonight. The comet will be visible near the Pleiades cluster. Mars will be visible within 2 degrees of the comet. See map below.
Magnitude > 6, hence binoculars or a telescope will be needed.

Nice shot of Comet C/2022 E3 (ZTF) along with planet Mars, taken by Michael Jäger yesterday from Austria.
Comet C/2022 E3 (ZTF) is still sporting its two tails (dust and ion) as it races away from the Sun to back home in the Oort cloud.

Hmm, think that's about as much as I'm gonna get out of this one #Comet #C2022E3 #Astrophotography (Canon G7 X, 160x8s, ISO 800)

Not enough movement for a simple median to really kill the stars, but does tone them down quite a bit. Quite a bit of tail there, but not sure I can make a pretty picture out of it #Comet #C2022E3 #Astrophotography

#Comet #C2022E3 on Jan 30. Not sure how to stack this one 🤔 #Astrophotography

Finally got a view of #comet C/2022E3 (ZTF)! Only had a few minutes before the clouds rolled in (again).
Still much processing to do though.
This is 27 x 3 second exposures with a Nikon Z50 with a 300mm lens on a tripod (no star tracker).
I *really* need a better setup for #astrophotography.

This is my best photo of Comet C/2022 E3. This green comet passed Earth for the first time in 50,000 years. It was last visible in the night sky during the Stone Age. 48,000 b.c.e.

But we have had gray skies forever (of course right?).

Nikon D750, 510mm 80ED OTA on tracking mount. If you want more details, just ask.

Look up! You can see a bright green comet making a rare trip across the Earth’s sky

It’s prime time to see the comet known as C/2022 E3, marked by its bright green nucleus and long faint ion tail. The comet has been visible for some time with telescopes and binoculars — but the best chance of seeing it with the naked eye is coming up on Wednesday, Feb. 1.

This marks possibly the first time ever — or at least for thousands of years — that the comet has streaked across our sky.

Overnight 31st Jan '23 I imaged #Comet C/2022 E3 (ZTF) with a #Canon1100D + kit lens for 9 hours from Oxfordshire, UK. You can see the tiny comet moving around Polaris as the Earth rotates, but also see how fast it was moving against the background stars. The video is too big for a direct upload, but it's on You Tube here: https://youtu.be/y3N2Q7yjTzk #C2022E3 #ZTF

Long orbital period is long.

Also, since it seems to have gotten lost in some of the news coverage:

#C2022E3 has an orbital period of about 50,000 years.

It is very much not a "once-in-50,000-years" event. There are tens of thousands of comets like it.

Nie, zeby mialo ja byc jakos bardzo dobrze widac golym okiem 😆

Tra oggi e domani avremo il picco e il momento migliore per osservare e fotografare la cometa C/2022 E3.

And here it is! Comet ‘C/2022 E3 (ZTF)’!

This image is a stack of 9 images, each taken with 30s of exposure. I configured the stacking software (Lynkeos) to track the comet instead of the stars in the background, hence they look blurred while the comet looks stationary.

Taken with a Nikon Z 6ii, AF-P Nikkor 70-300mm (@300mm), ISO 640, 30s, ƒ/5.6. All mounted on a Sky-Watcher EQM 35 WiFi go-to azimuthal mount.

Woah. So… I thought I had messed up my stacking logic, but turns out I used such long exposures that I captured the comet's movement!

It also displays LEO satellites which unfortunately light-pollute the night sky.

The comet's ion tail is formed as a result of ionization of particles in the coma by solar ultra-violet radiation; the particles are then propelled by the solar wind.
The ion tail tends to be long and narrow. The ion tail shines through fluorescence and is blue in color. The dominant CO+ molecule in the tail absorbs sunlight which it then re-emits at the blue 420 nanometer wavelength.

Like other comets, C/2022 E3 (ZTF) has a dust tail trailing behind the comet and a glowing ion tail, pointing away from the Sun, formed from gases ionized by UV radiation from the Sun.

The dust tail is also affected by solar radiation and hence is oriented a bit away from the sun.

Here is an updated light curve from http://astro.vanbuitenen.nl/comet/2022E3 with magnitude (brightness) values of Comet C/2022 E3 (ZTF). This graph predicts a magnitude value of around 5 on Feb 1, at closest approach to earth.

Objects with lower magnitude values are brighter. The human eye can detect objects with magnitude < 6. With a good pair of 10x50 binoculars, one can observe objects at magnitude 11 and lower .
