COMET ISON OUTBURST: Observers around the world are reporting a sharp
increase in the brightness of sundiving Comet ISON. Formerly dim, it is
now on the threshold of naked-eye visibility. Comet ISON is plunging
toward the sun for a perilous pass through the solar atmosphere on
Thanksgiving Day (Nov. 28th).
This could be the first of many brightening events as intensifying
solar heat erodes material away from the comet's nucleus.
