COMET EXPLOSION: Almost 450 million km from Earth, Comet C/2012 X1 (LINEAR) has exploded. Amateur astronomers are reporting a 100-fold increase in the comet's brightness compared to predictions, and the comet's atmosphere or "coma" now resembles that of exploding Comet 17P/Holmes in 2007.
...........................Located in the constellation Coma Berenices, Comet LINEAR X1 rises in the east about an hour before the sun.
