The Comet is Dead - Long live the research

This evening I shared with other members of the CIOC_ISON group the loss of a comet that did not live to see whether it was to be the Comet of the Century, a label promoted by the Media, rather than those who have spent many months of their lives following its progression in its orbit which it thought started in the Oort Cloud only to see it destroyed when it came close to the Sun.

We joined, with many others, the NASA ISON Google Hangout watching the progress of the comet through the use of a number of space telescopes including SOLO and STEREO.

When the Hangout finished we all drifted off - many to Thanksgiving Meals - with many giving a silent toast to this comet that had become part of our lives. Some will feel that they have lost a friend, others will feel that along with a hole in their lives.

There still remains something, but whatever there is can be no more than a ghost of the comet. there will be the dust thrown off and maybe some small fragments. I, along with others, will be trying to image this ghost in a week or so, but even if we are successful they will not be the images we had all hoped for.

ISON may be gone, but the work has not finished. The many observations of ISON are there for further research to take place because in its journey towards our Sun and its dying our understanding of our Solar System will be better understood.

I will certainly be examining the images taken, starting with the days leading up to the image I took of the disruption on the morning of the 13th of this month.



  

Was this the start of something that the Sun on gave the final blow. I do not know, but I am think that this is an area that needs questioning. It was only two days later when something else happened.





These are quite extreme changes - say I with so limited an experience in this area. Soon after it changed again - settling down?



Now these are just three of many images of ISON that I have taken during the past weeks. I am just one observer amongst many, so there must be thousands of images out there from which a complete illustrated history could be derived.

This is one of the reasons that I am glad that I am able to be part of the CIOC_ISON NASA ProAm Group led by +Padma Yanamandra-Fisher . This is exactly one of the many things that Padma is doing, Creating a timeline of observations that will be held in a database that can then be fully analysed by the ProAm community she has assembled.

The Comet may be dead, but the research and discoveries that will come from the observations will live on long after the general public have forgotten ISON, something of course we will never do.
