Reports of fading, elongation and bimodal light distribution have been out for a day or so...

And now the 'double nucleus' can be imaged by humble mortals.

 

A 2.6' wide image of the head of the comet:

And sharpened:

 

c2019y4-20200406-610-1_sc_crop_itgauss2.jpg

 

The nucleus appears like a bar-bell, with maxima ~3" apart, much as reported in the Telegram above. This is one hour of images - will add the second hour shortly.

 

Theres also another possible bright patch trailing - not sure if this is an artifact or not. I dont think so. The second hour should clarify.

NOooooo -- we don't want it to break up!  It was supposed to be a naked-eye "Great Comet"!  undecided.gif

Outstanding job. 

 

I was trying to image T2 and Y4 last night, but the light pollution in Chicago is too overwhelming and my experience with this kind of objects is not good.

 

I did however notice that T2 looked brighter and more condensed. 

 

Here is my image of T2 (PANSTARRS) last night:

T220200406

 

And here is my Y4 (ATLAS):

ATLAS20200406
 
Exposure, processing and equipment is all the same. I was expecting Y4 to be brighter, but it was not.
 
Cheers,
 
Jose

Bloody ripper captures, mate!

 

With a DEC at 68˚, its apex is 1˚ below the horizon for me…

Oh dam! I'm under clouds and rain.

Stinking weather!

 

So we might still get some comet chunks later on.  shocked.gif

i got the images under full moon though - so probably no worse than central chicago!

 

Yeah, your images also tell the story. Nice to have the comparison with T2

Central Chicago is worse than a full moon.  Making matters worse, the only time there are no clouds in Chicago is when there is a full moon.

I'm still hoping for a chance at this. We've only had one real clear night in the past month and that had 20-25mph wind. Maybe Friday night...maybe...we've been excelling at clear days and cloudy nights though...

Mere mortals?  That's a high bar for this mortal.  Nice capture.

Well, the break-up itself is a spectacular event at least! Fantastic captures. 

 

For me this comet is too close to the horizon in a country that's obsessed with bright lights, so I was always going to live vicariously through you all anyway.  :)

These are spectacular images!

Breakup might make it even more memorable.  Reference 3/D Biela's Comet,  Comet West C/1975 V1 and others.
