C/2012 X1 (LINEAR) - Oct 2013

C/2012 X1 (LINEAR) 
(Passing through starfield in Coma Berenicies. Sun Distance 2.25 AU)

Located around 450 million km from Earth, Comet C/2012 X1 (LINEAR) has undergone an explosive eruption sometime around 
21st Oct (2013-10-21). Amateur astronomers report that it underwent a 100-fold increase in the comet's brightness 
compared to its predicted brightness.  (Spaceweather.com  page for 2013-10-22)
The comet's atmosphere or "coma" now resembles that of exploding Comet 17P/Holmes in 2007.
