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. For more information and updates, visit http://spaceweather.com
