The comet C/2012 X1 was discovered on December 8th, 2012 by the Lincoln Near Earth Asteroid Research (LINEAR) survey based in Socorro, New Mexico. Comet X1 LINEAR was expected to peak out at about +12th magnitude in early 2014. That changed on October 20th 2013, when amateur observers began to report a swift change in brightness for the comet. Japanese observer Hidetaka Sato reported the comet magnitude to be +8.5 on October 20th, a full 5.5 magnitudes above its expected brightness of +14. Also, this means an increase in brightness of 100-fold. This image was taken on December 4th 2013 between 5:40 and 6:10 LT ( 2:40 and 3:10 UT)
