Discussion Overview

The discussion revolves around the comet ISON, focusing on its current status, visual observations, and related astronomical phenomena. Participants share updates on its distance from the Sun, speculate on its visibility, and discuss visual artifacts in images of the comet.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants provide updates on ISON's distance from the Sun, noting a decrease from 7,933,146 km to 7,515,184 km.
  • A live stream of ISON's perihelion is shared, indicating an event occurring shortly after the post.
  • There is speculation about the visibility of ISON to the naked eye, with some expressing hope that it will be large enough to see.
  • One participant comments on ISON appearing to be "shredded" by the Sun, suggesting a significant change in its visibility and structure.
  • Participants discuss the identification of celestial objects in images, with one asserting that a bright object is the star Antares, while another questions this identification.
  • A suggestion is made to use planetarium software, specifically Stellarium, to verify the positions of celestial bodies.
  • There is a humorous reference to a Shakespeare line regarding the perceived demise of ISON, with a participant expressing optimism about its condition.

Areas of Agreement / Disagreement

Participants express differing views on the current state of ISON, with some believing it has been significantly damaged while others remain hopeful about its visibility and integrity. The identification of celestial objects also sees conflicting opinions.

Contextual Notes

Some claims about the visibility and condition of ISON depend on observational conditions and individual interpretations of images, which may not be universally agreed upon.

Who May Find This Useful

Astronomy enthusiasts, comet observers, and individuals interested in celestial events may find this discussion relevant.

No, that is the bright star Antares. The "ring" is a CCD camera artefact caused by electrons from oversaturated pixels leaking into adjacent pixels.

Thanks..
But how do you come to know that it was Antares and no one else?
 
use a planetarium program to see where the sun is amd what the surrounding stars are

Stellarium is a good choice

Was it a Shakespeare line that said?

" the rumours of my early demise have been greatly exaggerated"

haha ... ISON still seems to be reasonably intact ... will be interesting to see how it looks when over the next week or so it gets picked up visually
