As many know, ISON will have a close encounter with the Sun. It is estimated that ISON will swing around the sun at an estimated 1.16 million kilometers from the star's surface on November 28th. Astronomers expected to see a "jaw-dropping" display across the sky.
We did a quick report late last month on ISON in which it was estimated to come within 750,000 miles of the sun's surface. In the NASA link in the earlier story it was said that the core had already began to break up but last week NASA'S Solar Terrestrial Relations Observatory (STEREO) took an image that indicates the core is largely intact.
Angelos Vourlidas of the Naval Research Lab and NASA's Comet Ison Observing Campaign (CIOC) has this to say; "near the peak of the solar cycle and eruptions are more frequent Ison will pass 30 times closer to the sun than Encke was in 2007." This could indicate that ISON might take some serious pounding when it approaches the sun.
