Comet ISON will continue to brighten throughout the month as it nears its late November perihelion (closest point to sun). ISON will pass very close to the bright star Spica and the planet Saturn, both in the constellation Virgo. Its perihelion on November 28 will be an exciting time. The comet will come within 1.2 million km of our sun’s surface. If all goes well, and the comet doesn’t break up (as comets sometimes do), the terrific heating Comet ISON will undergo when it’s closest to our parent star might turn the comet into a brilliant object. Some are predicting that ISON will become as bright as a full moon! That would make Comet ISON a daylight object, briefly. Remember, though, at perihelion, Comet ISON will appear close to the sun on the sky’s dome (only 4.4° north of the sun on November 28) Impossible and Dangerous for us to try to find ISON.
