Fragments Of Comet C/2019 Y4 (ATLAS) Start To Brighten, Per Ace Comet Hunter Terry Lovejoy.

The first set of imaging is by veteran comet hunter Terry Lovejoy — who has discovered 6 comets. He knows his stuff & his forte is astrophotography. His pictures show that one fragment has brightened noticeably. This could be because it is getting ever closer to the Sun and as such continuing to become more ‘active’ — i.e., ‘evaporate’ giving out gases.

The comet has definitely fragmented. Of that there is no doubt or debate. The ‘orange’ Hubble picture shows 4-fragments and JPL (2nd image) already lists 5.

As the orbital diagram shows the ‘comet’ — or to be more precise — the fragments are still a longways out and we are moving away.

The fragments may be bright, but they are SMALL. So naked-eye visibility is questionable.

Hubble Imaging Shows Comet C/2019 Y4 (ATLAS), Alas, Continuing To Fragment.

C/2019 Y4 (ATLAS), as I told you last week, has started to fragment.


Some very clear & graphic imaging on C/2019 Y4 (ATLAS) from Hubble.

You can clearly see that it continues to break-up. It will NOT be naked-eye visible. SORRY.

Hopefully C/2020 F8 (SWAN) will step in. I am keeping an eye — quite literally.

Comet C/2020 F8 (SWAN) Steps In As Naked-Eye Candidate C/2019 Y4 (ATLAS) Fizzles.

A brand new comet, discovered in March 2020 — hence the ‘2020 F’ (6th half-month of 2020).

SWAN denotes that it was found by the Solar Wind ANisotropies (SWAN) instrument of the SOHO spacecraft studying the Sun.

Its perihelion date is May 27, 2020.

It could become naked-eye visible in a few weeks. I will keep YOU posted. Promise.

Comet C/2019 Y4 (ATLAS) Unlikely To NOW Be Naked-Eye — It Is Breaking Up.

SHAME.

But, I did say, very clearly — DO NOT GET YOUR HOPES UP.

I was hoping. I would have liked to have seen another naked-eye comet. The last was 23-years ago! That is too long.

There is a WHOLE generation, in the Northern Hemisphere, that have never seen a naked-eye comet. (Yes, there have been a FEW in the Southern Hemisphere.)

That it started breaking up this far from the Sun is incongruous. But, it is travelling at breakneck speeds, getting faster by the second.

Well, that was THAT. SMILE.

Wait for another.

Waited 7-years for this.

I fully understand that they must be getting a few hundred thousand hits per second.

BUT, we all knew that this would happen — and that it would happen today.

NASA, if it wanted, had PLENTY of time to increase their server capacity.

You are NOT talking about me and my economy hosting at GoDaddy.
But, even I managed to increase my capacity on the fly
when the pope resigned and I was getting huge spikes in traffic …

They have billions of dollars worth of IT infrastructure.

They have supercomputers!

They are supposed to be the shining example of U.S. technological superiority.

As far as I am concerned they have screwed up AGAIN — and here are two other examples;
example 1 & example 2.

No wonder people don’t trust the U.S. government. This is such a shame.

The head of NASA should be run out of town, impeached or whatever.
Basically fired.


Comet ISON, IF It Fragments, Could STILL Be A Great — Fragmentation Possible Even After Today’s Perihelion.

Fragmentation of Comet ISON was always on the cards.
Check my book.

But, as I have also always maintained (in my books) fragmentation, unless it is totally disastrous, does NOT have to be the end of the world.

Comet Ikeya–Seki, in 1965, C/1965 S1, THE BRIGHTEST comet seen since 1935, another Sungrazer like ISON (but one that went even closer) FRAGMENTED during perihelion.

That proved to be GOOD!

Why? The 3 main pieces stayed close together. But, now there were much, much more exposed surface area. So more of the frozen matter could sublimate (‘evaporate’). It is this sublimation which creates the coma and tails — which in turn is what makes a comet great or not-so-great.

So, fragmentation is OK — unless the comet gets pulverized, i.e., turns to a cloud of dust as did 2010’s Comet Elenin, C/2010 X1 — thought by some, totally irrationally, to be a doomsday comet, Nibiru. Well, that didn’t happen. A gauzy cloud of faint dust isn’t going to damage Earth!
