'Devil' comet visible tonight 21.04.24

[pinball1970]

TL;DR Summary

Viewers in the mid- to southern latitudes of North America can look toward the Taurus constellation immediately after sunset to spot the comet. It will be just below the constellation, with the prominent 'V' shape of Taurus pointing down towards it. The comet will appear just to the left of Jupiter.

From the article:

"Viewers in the mid- to southern latitudes of North America can look toward the Taurus constellation immediately after sunset to spot the comet. It will be just below the constellation, with the prominent 'V' shape of Taurus pointing down towards it. The comet will appear just to the left of Jupiter, which will appear as a bright pale yellow orb.
Look for a circular, wispy patch of light with possibly a faint tail that stretches up and to the left of the bright central area, or coma, that surrounds the comet's nucleus."

I think that will be tricker than the article assumes. It is very low in the sky and close to the sun, twilight and atmospheric absorption will be serious problem.

Let's see if any of the pf beautiful universe guys get an image.

They can probably get something. It is just a pity that these kinds of articles always gets published for perihelion. If the comet is close to the sun in the sky it is much better to observe it, depending on the shape of its orbit, earlier (like in this case, it has been followed visually since November and was really nice a few weeks ago), or later like with C/2011 L4 Pan-STARRS in 2013 (impossible to spot when the massive press and TV news coverage said but very nice naked eye a few weeks after when only amateur astronomers still cared).

It'll be back in the night sky in the Summer [for the Southern hemisphere]... (June, mostly, if I remember correctly, though even in May will start being ok to spot etc. ...). Now it's really the worst time to observe it or get photos ...
Quoting from Spacewether.com :
A) [April 22]
"THE 'DEVIL COMET' AT PERIHELION: Comet 12P/Pons-Brooks hasn't been this close to the sun for 71 years. On April 21st, the 'devil comet' reached perihelion at a distance of 0.78 AU. Solar heat brightened the comet, but sky watchers couldn't enjoy the show. This animation from Mike Olason of Tucson, Arizona, shows why:

The comet is very close to the horizon when the sun sets. Bright twilight almost washes it out. Add in this week's full Moon and you have a very tricky observing problem.

"The comet is getting closer to the horizon each evening as twilight is getting brighter," says Olason. "By the end of the month 12P will no longer be observable from here in Tucson."

Now for the good news: In May, the comet will move away from the sun and into the night skies of the southern hemisphere. In fact, astronomer Michael Mattiazzo is already seeing it from Australia."

B) [April 21]
"THIS IS THE WORST TIME TO OBSERVE 'THE DEVIL COMET': If you get your science news from mainstream media, you might think this weekend is a great time to observe Comet 12P/Pons-Brooks, a.k.a. "The Devil Comet." In fact, the opposite is true. The comet--barely a naked eye object on the best of nights--is almost completely overwhelmed by a combination of evening twilight and full Moonlight.

To illustrate the problem, Mike Olason photographed the comet sinking into the haze near of Tucson, Arizona, on April 20th:

"As one can see from the animation, the images were collected as twilight started to fade only to be replaced by moonshine from the 87% illuminated Moon," says Olason. "It also did not help that the comet was at an altitude below 6 degrees. Most of the tail and coma were washed out by light pollution, twilight, Moonlight and atmospheric interference."

The kernel of truth in mainstream reports is that Comet 12P is at perihelion on April 21st--its closest approach to the sun. Solar heat is indeed brightening the comet to its maximum luminosity. However, Earth and the comet are far apart on opposite sides of the sun, and we have to squint through the glare of the sun to see the comet.

It all adds up to poor visibility--for now. In May the comet will move away from the sun and into the night skies of the southern hemisphere. In fact, astronomer Michael Mattiazzo is already seing from Australia." (see above for the link ...)

yeah, still very close to the horizon here in Australia. I have seen/photo'ed it a couple of times but very difficult in the twilight
this was for the 22 April that I posted on social media .....

TONITE'S "BEST OF THE BUNCH" PHOTO OF COMET 12P/PONS-BROOKS​

Canon 6DII, 200mm, f2.8, 10 sec, ISO160
unguided hence the star trailing, but a fuzz of a tail is visible
Area finder map as well
Comet was on the line at 10o'clock from that star just above the "h" of 20h
Shooting to the NW from West Ryde, across a major portion of the Wstrn/NW suburbs of the city. Would have been better from a dark site.
Wasn't visible in 7x50 binoculars

Thanks @davenn for this live observation update from the Southern Hemisphere ...

 

[Skywave]

Another update from Southern Hemisphere (this time South Africa). Was very low on the horizon. I focused on 29 Tauri and moved just slightly off centre, as I didn't know if the tracking on Pons-Brook would be very accurate.

2 minute total exposure time, at 10sec exposure intervals, Seestar S50 smart telescope.
(Focal Length 250mm, Aperture 50mm, f/5; 1920x1080 pixels, pixel dimensions 2.9μm square, sensor diagonal 6.46mm, aspect ratio 1/2.8)

Wow! great!

Let's see if any of the pf beautiful universe guys get an image.

Despite the status and issues ... doing great so far (see posts #8 & #6 above ...)
