WATCH | Comet ATLAS Disintegration Live Stream! – It looks like Comet ATLAS is disintegrating.

So tonight at 10pm eastern, 2:00 UT, I’ll stream comet ATLAS as it starts to fade and disintegrate:


Astronomers Quanzhi Ye (University of Maryland) and Qicheng Zhang (Caltech) submitted an astronomical telegram titled Possible Disintegration of Comet C/2019 Y4 (ATLAS). According to their telegram:

We report the possible disintegration of comet C/2019 Y4 (ATLAS), revealed by the public monitoring program carried out by the 0.6-m Ningbo Education Xinjiang Telescope (NEXT). Images taken on UT 2020 April 5.6-5.9 showed an elongated pseudo-nucleus measuring about 3 arcsec in length and aligned with the axis of the tail, a morphology consistent with a sudden decline or cessation of dust production, as would be expected from a major disruption of the [comet’s] nucleus.

Does this mean the end of Comet C/2019 Y4 (ATLAS)? Not necessarily. Time and time again, comets have shown themselves to be erratic and unpredictable. In case Comet ATLAS does remain visible – and in one piece – EarthSky shares some charts below to help you find the celestial visitor.
