Space enthusiasts are worried about Comet ISON, which will reach perihelion, the point in its orbit closest to the sun, on Nov. 29. The cause of their concern is that its brightness has not increased as predicted.
The approach of Comet ISON has been billed as the biggest astronomical event of the year, as astronomers assumed its brightness would reach a magnitude of minus 13, or slightly more brilliant than a full moon, when the comet was discovered in September last year.But the pace of the increase in the comet's brightness has been slower than predicted.
The best times to observe the comet will be an hour before dawn on Dec. 4 to 10, when it will be moderately distant from the sun. During those times, the comet will be visible in the lower part of the eastern sky.
