<tinfoil on>
OMG!!!!1111!!!!
Another comet!!!!1111!!!!
Where are they all coming from?!!!!1111!!!!

Could this one be the Blue Kaching! -a?
Or NibbleU? Or Wormywood? Or The Destroyer? Or The Battleship? Or The Aircraft Carrier?
Why did NASA only discover this yesterday March 13 2014?
Hmmmm... March 13 2014 = 3 13 2014 = 77 and 7x7=49 and 4+9=13 the number of death.
It was only 2au from the sun when it was discovered!!!!
How come NASA and Professional Science didn't discover it when it was out by Jupiter?!!!!
What are they hiding??!!!!??
How big is it?
Can it hit Earth?

And most important of all...
What about its DEBRIS TRAIL????!!!!
</tinfoil off>

Hydra, maybe you should make 30 or 40 Rubetube vids on this comet and make it seem as mysterious and ominous as possible by Just Asking Questions... commonly referred to as JAQing Off.
If you'd done that for this thread it would be at 50 pages by now.

Back to reality.
Good thread with factual information about something that actually isn't a delusion.
Thanks.

Have fun.

Here's my first shot of it about an hour ago or so (a composite of star-aligned and comet-aligned stacks) using my 8" LX200 and SBIG ST-7.

More to come.

Nice pic.
I'll have to wait until August to catch it - the April observation window don't work for me: to much light pollution in the South.

.

Thank you Hydra.

Thanks! Yeah, it's not exactly ideally placed for me either, but I'm pretty happy with the images I was able to get. Here they are in a time lapse animation rather than a stack:

Here's the color version of the image.

Very nice animation. Lets hope it's nice and bright come August.

Thanks for the images Astro.

What's "most interesting" about the orbit?

The only "most interesting" thing I can see is that NewTard had a verbal ejaculatio praecox about the orbit, based an 65 observations spanning just 1 (one) day.

C/2014 E2 is "passing by each planet close enough to high five them, right?"
For a High Five at a distance of 50 to 80 Million kilometers you must have quite long arms.

And "it comes very close to Mercury"?
For a High Five, too?
Yep, then Venus and Mercury have a High Five twice a year.



.

Exactly.

Close Approach distances using current data (via JPL):

Mars:
2014-Mar-21 22:00 : 111,487,211 km = 69,274,941 miles

Earth:
2014-Aug-29 19:00 : 85,575,356 km = 53,174,061 miles

Venus:
2014-Jul-14 10:00 : 11,426,306 km = 7,099,978 miles

Mercury:
2014-Jul-20 19:00 : 69,137,706 km = 42,960,179 miles


In his latest video about C/2014E2 NewTard said, "Yeah, it looks like it's going to hit Mercury; kind of looks like it's going to hit Venus; Earth's going to get a very close pass to it, but there's no DOOM (sarcastic); Mars is going to get a close pass to it."

and,

"Very close to Mars; pretty close to Mercury; SUPER CLOSE to Venus; and kind of close to Earth ..."

and,

"That just means it's going to drop its nutrient dust on our planet and maybe help fight the global climate warming-change."


Yeah Tard, this comet is going to "drop dust" on Earth from 53 million miles; from 2.1 times the Earth-Venus distance of Jan 10 2014.
You just will not stop lying, will you?

In this universe, passing Mars by 69 million miles and passing Mercury by 43 million miles isn't considered "close". In fact it is considered very, very far.

The only close approach is to Venus, and I'm sure you'll misunderstand enough to produce a few disinfo vids about that encounter.

Someone may need to make a thread debunking your latest piece of trash on C/2014 E2 (JACQUES).

"... the people who are in charge of astronomy don't want us talking about astronomy." -
No, they just don't want liars and morons such as you spreading ignorant disinfo that they have to constantly combat and correct when if you would just tell the truth everyone would be content.
Yet you continue to lie and exaggerate to make circumstances seem more ominous.
Why is that, Tard?

You could be just as "funny" telling the truth and skewering the kOOks and Doom liars as you are now telling lies and skewering scientists who tell the truth.
But you choose the former.
Why is that, Tard?

Also, I note you didn't take down and correct your vid:
Influx of Asteroids! & Asteroid 2014 DX110 to pass between Earth & Moon!
[link to www.youtube.com]
Even after it was shown that there was no increase in NEAs, and in fact the 18 you were babbling about were, in fact, on the low side of what could be expected.

You left that little piece of disinfo up for your sheep to graze on even though shown to be in error.

What an honest guy...

kOOks lie. Constantly. It's part of the job description.

Where did I mention the close approach to Venus?

Trying to divert from your stupid claims, NewTard?

.

It is close as far as cometary encounters go, but still quite far away in actual distance so...
What is your point?

Why don't you tell us how "BIG" Jacques nucleus is?
You are making vids about this so you must have some knowledge or are you just JAQing off to make this comet seem mysterious and ominous?

Come on "researcher" why don't you tell us some correct information for once in your life?
How big do you think this comet's nucleus is?
(We're about to find out if you are a McCanneytard)

Please provide a reason for your estimated size.

C'mon NewTard, show us your stuff.

I guess you take opinions as facts which is quite sad to a point almost humorous. Would love to see a refute youtube vid from yourself on all the recent comet and space junk flying around our happy little earth.

I got myself a scope now so can I join astronomy squad???
Or will I get slammed or berated from people who never venture more then 20ft from their computers?

Making, how many videos about ISON - you try to tell us you don't know how to look at orbits from different angles?

How stupid do you think the GLPers are?




I didn't know that cometary orbits are subject to opinion, imagination and humor.


.

I deleted two posts of you because OFF TOPIC.

This thread is about Comet C/2014 E2 - not about Obama, Climate Change or asteroids.


NO OFF TOPIC

NO DERAILMENT

I couldn't care less about your idiotic patter when presenting your infotainment.
In case you haven't noticed, I am attacking your lies and twisting of the facts which is why you are trying to change the subject and build a strawman about your "comedic" presentation.

On your "3 asteroids passed ...":
Are you finished moving the goalposts then?
This is the 3rd iteration of your original claim as you found yourself cornered by your lies in the previous two.

How about you tell us if "3 asteroids passed..." is unusual?
Surely you can do that minimal amount of research.
It is, after all, central to your claim that "18 NEAs in 8 days" is unusual.
Or "3 asteroid passed..." is unusual.
You've made the statement that they are unusual.
You've argued against evidence that they are not unusual.

And now you mean to tell us you made these statements and you are now admitting you don't know if they are factual?

And you want the debunkers to look up the info for you?
Pull the other one...

Lying Tard.

What part of:
"In this universe, passing Mars by 69 million miles and passing Mercury by 43 million miles isn't considered "close". In fact it is considered very, very far."
did you fail to understand?

If you're opinion is that missing Mars by 69 million miles is "close" and "Very close" you're idiotic opinion deserves all the ridicule that can be heaped upon it.

From your post I take it that you are a fan of lies and liars if they are telling the lies you approve of.

First light curve for C/2014 E2 from Seiici Yoshida:

:c2014e1-light1:

My estimation is a little more optimistic (blue curve, based on the brightness of the initial observation):

:c2014e1-light2:

.

Some thoughts about C/2014 E2 (Jacques).

The MPC gives the eccentricity of C/2014 E2's orbit as e = 1.0, a parabolic orbit. But this number is based on only about 60 observation data.

An eccentricity of 1.0 or greater indicates a comet that never before made a trip into the inner solar system, a "dynamically new comet". Dynamically new comet have a lot of volatiles that sublimate at low temperatures, at temperatures present beyond the orbit of Jupiter, like CO, CN or Methan. C/2012 S1 (ISON) e.g. was dynamically new and was discovered beyond the orbit of Jupiter.

The question is: Why was C/2014 E2 only discovert just outside the Mars orbit?

The Mars orbit is the threshold for the sublimation of water ice. Most likely C/2014 E2 is not a new comet (has an eccentricity smaller than 1.0) but is a periodic comet with a periode of some thousand or even some hundred years. During previous travels around the sun it had lost all volatiles sublimating at low temperatures. What remains is mainly water ice that starts sublimating only a short time ago and led to its discovery.

I'm quite sure that, with more observations taken into account, the final orbit will be periodic. (And for the dimwits, which didn't learn their lesson from ISON: No, it's not the orbit that changes - the calculation just give better results with more data).

The good news (based on the assumption above):
Since C/2014 E2 (Jacques) orbited the sun in the past without breaking up, it's unlikely that it will break up now.
The discovery brightness of around mag 11 indicates that the comet still holds a lot of water ice and that he will not be a dud.

But remember: Comets are like cats ...
C/2014 E2 may hold some surprises - I'm optimistic and think: positive surprises. (But negative surprises are possible, too).

.

More observation and better calculations - as I had expected the new calculations reveal C/2014 E2 (Jacques) as a periodic comet with an orbital periode of 24,676 years.

[link to ssd.jpl.nasa.gov]

Thus we can expect a quite stable comet that should be a nice binocular object (with luck naked eye object) in August / September.

.

Nibiru?

With almost 1800 observations the orbit was established now as long periodic (25,830 years).
[link to ssd.jpl.nasa.gov]


And there are good news: The brightness development is above the original estimated lightcurve.

If the comet follows the new lightcurve it will reach a max brightness of mag 4.4 around perihelion.
It would reach naked eye visibility (mag 6) from middle of June until middle of August .... but ....

.... unfortunately it will not be visible before middle of July - the dates are to close to the summer solstice in the northern hemisphere, the comet will be outshined by the suns glare.

Some rough estimates from what dates the comet will be visible:
Australia, southern Africa, southern South America: End of July low in the sky at ENE.
Equator region: Middle of July low in the sky at ENE.
Japan, Mediterranea sea, Central USA: End of July low in the sky at ENE.
Russia, Germany, United Kingdom, Canada: Beginning of August low in the sky at ENE.


New light curve = blue - Original light curve = red

Hydra, will I be able to see Jacques with a small telescope or binoculars. It was great seeing PANSTARRS and Lovejoy last year ( you know which ones ).

From a couple of weeks ago:

[link to www.universetoday.com]

Suggesting magnitude 6.5, possible in 10x50 binoculars and again from a few days ago:

What do you think?

Hi K.

The first photo I took on July 31. was just with a simple DSLR f:250mm. I estimate the brightness at 7 to 7.5 mag from the surrounding stars.
The second photo on August 6 was taken with a 10" SC in prime focus - magnitude about the same.

The comet is receding from the sun but is coming closer to earth. Thus the magnitude is only dropping slightly - should be around mag 7.5 to 8 at the moment and will start dropping faster from Aug 21.

If the light pollution in your area isn't to big, it should be an easy target for a small telescope.

.

Thanks, I am not sure how practical this one will be for me then, as I have all of London to my North East! Otherwise it's an early morning trip out into the North Downs.

If you can see Algol it should be ok. But at the moment the light of the Moon is unfavourable.

Michael Jäger is an extraordinary comet hunter and photographer. And he has an optimal sky.
